		<title>NWS Budget Cuts</title>
		<link>http://www.americanwx.com/bb/index.php/topic/32670-nws-budget-cuts/</link>
		<description><![CDATA[Press release from the National Weather Service Employees Organization:<br />
<br />
<br />
<strong class='bbc'>	<strong class='bbc'>President Obama’s 2013 Budget Plan Cuts Crucial Positions at Weather Forecast Offices,<br />
	Jeopardizing the Lifesaving Mission of the National Weather Service</strong></strong><br />
 <br />
<p class='bbc_left'><br />
(February 13, 2012) Less than nine months after commenting that Republican-led budget cuts “might compromise the National Weather Service,” the President’s 2013 budget proposal calls for damaging cuts to the NWS, including cuts to positions critical to emergency responses at weather forecast offices (WFO).  </p>
<br />
<p class='bbc_left'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'>The cuts would decrease the number of information technology officers at weather forecast offices across the nation.  Currently, each WFO is staffed with one local programmer/IT specialist (ITO) who is critical to NWS operations. During an emergency response, ITOs are crucial to the WFO’s local ability to innovate immediate lifesaving products and services.  Because ITOs are meteorologists with information technology skills, they are frequently used to cover shifts and assist WFOs during severe weather, in addition to their regular duties.  Most WFOs are only fair weather staffed, meaning there are not enough meteorologists to cover shifts during severe weather outbreaks. The NWS service assessments on the historic 2011 tornados and the 2010 Nashville flood event commended offices for having ITOs on station during the event to help with weather and IT issues.</span></span></span></p>
<br />
<p class='bbc_left'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'>“The ITO position is crucial to the lifesaving work of weather forecast offices,” said NWSEO President Dan Sobien. “These are the guys who ensure our technology is working and our forecasts are accurate. Without an ITO on site, responses will be slower and lives will be lost during extreme weather events. This is an alarming move backwards when it comes to protecting the public.”</span></span></span></span></span></span></p>
<br />
<p class='bbc_left'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'>Additional 2013 budget cuts propose eliminating research on improving hurricane intensity forecasts and the air quality forecasts.</span></span></span></span></span></span></span></span></span></p>
<p class='bbc_left'><br />
<span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'><span style='color: #4C2F18'><span style='font-family: arial, verdana, sans-serif'><span style='font-size: 12px;'>“Seriously, with all of the money government wastes, are we going to cut the people who are integral to the tornado warning process?” asked Sobien. “I think if the federal government can afford $39 million for the Blue Angels and $325 million for marching bands, it can afford $15 million to provide its citizens warnings of severe weather. It may not be this year or next, but if these cuts go through, the nation will see another Katrina-like event, and it could have been entirely preventable.”</span></span></span></span></span></span></span></span></span></p>

		<title>Medium Range Discussion Winter 2011-12</title>
		<link>http://www.americanwx.com/bb/index.php/topic/29440-medium-range-discussion-winter-2011-12/</link>
		<description><![CDATA[Time to fire this thread up again for winter. Hopefully, this year it will be more than Jorge and me talking to ourselves.<br />
<br />
For the next ten days or so, it looks to be cool west/warm east with intermittent shots of cool behind shortwaves in a typical -PNA/gradient flow pattern. The big question is when will the pattern change? Judging by the <a href='http://www.atmos.albany.edu/facstaff/roundy/waves/hovsdet/7.5S_7.5N/2011.png' class='bbc_url' title='External link' rel='external'>tropical convection forecasts</a>, I'd guess some time around Thanksgiving. As convection fires over the Western Indian Ocean, we should see ridging go up across the Rockies and allow cold air to filter down into the CONUS.]]></description>

		<description><![CDATA[It's never too early to start speculatin'. <img src='http://www.americanwx.com/bb/public/style_emoticons/default/sun.gif' class='bbc_emoticon' alt=':sun:' /><br />
<br />
Since we're entering the New Year, I thought I'd get the discussion going.<br />
<br />
Yeah, there were a ton of named storms in 2011, but by most yardsticks, the season was kind of a bust.  And the USA's major-hurricane drought has now gone on crazy long.  The last 100-kt 'cane to hit the USA was Wilma 2005!  The last time the USA went this long without a major was the period 1861-1868. Yikes.<br />
<br />
What's 2012 going to bring us?]]></description>

		<title>East Coast Winter Storm Potential</title>
		<link>http://www.americanwx.com/bb/index.php/topic/32761-east-coast-winter-storm-potential/</link>
		<description><![CDATA[The first and main thing is to know the pattern and then to know the <em class='bbc'>focal point</em>. The focal point refers to the time period when two things are present. 1.Cut-off energy originating in the Southwest United States. 2. An extensive cold front (moving all the way down into FL) are present.<br />
<br />
The 'extensive surface cold front/ temperature gradient' typically arrives<strong class='bbc'> shortly AFTER or DURING the Cut-Off passing in the East...It is associated with the Polar Energy. </strong><br />
.<br />
<span class='bbc_underline'>During Example:</span> October 29 2011 Historic East Coast Snowstorm. Most likely chance for a phase.<br />
<span class='bbc_underline'>After Example</span> (Most common scenario this winter): January 26 2012. No phasing in the East with the upstream energy...<em class='bbc'>Cut-Off moves into the area <span class='bbc_underline'>first</span>  (<span class='bbc_underline'>with the leading trough acting as a cold front</span>) and then the polar energy wraps around <span class='bbc_underline'>behind</span> it.</em><br />
<br />
1.The main idea is to have a <span class='bbc_underline'>phase</span> like we did in October--the cut-off in the subtropical flow phasing with the polar energy aloft.<br />
<br />
2.If the phase between the cut-off and the polar energy does <strong class='bbc'>NOT</strong> occur aloft, we are looking at a rainstorm and 50s or the storm passing to our south and east. <em class='bbc'>Most of the energy phasing into the leading trough moving in as a cold front.</em><br />
<br />
3.A <em class='bbc'>partial phase</em> (polar energy catching up to <em class='bbc'>some</em> subtropical energy aloft) will allow some snow to develop in selected areas to the <em class='bbc'>south and to the east</em> (e.g., South Jersey Event that occurred early on January 10, 2012).<br />

1.Cut-Off phases with the leading trough, <em class='bbc'>it comes in first</em> and delivers the warm, subtropical air to most of the East.<br />

		<title>Devastating tornado strikes Joplin, Missouri</title>
		<link>http://www.americanwx.com/bb/index.php/topic/18858-devastating-tornado-strikes-joplin-missouri/</link>
		<description><![CDATA[Posting this here as it may become a story of national interest...<br />
<br />
Obviously we have to wait for the survey but it looks like it may have been a violent tornado.  The tornado appears to have tracked across the southern portion of the city and quite wide.  It only happened a few hours ago and there are already reports of 24 deaths, but that number will probably rise.<br />
<br />
Joplin has a population of about 50,000.  This is the latest example of a major tornado striking a densely populated area, an all too frequent occurrence this year.<br />
<br />
We have a member from Joplin by the name of JoMo.  He was posting in the severe weather thread until the tornado approached.  It is unclear whether he was hit but we have not heard from him since the tornado struck.  Please keep him in your thoughts.]]></description>

		<title>Extreme Cold In Europe and Africa</title>
		<link>http://www.americanwx.com/bb/index.php/topic/32339-extreme-cold-in-europe-and-africa/</link>
		<description><![CDATA[The recent -AO has already caused some pretty crazy weather over the last few days. For example, pressures have been measured as high as 1060 hPa over portions of extreme northern Europe, including Norway, while the high center has been progged as high as 1064+ over in Western Russa. This extremely high pressure has also resulted in some pretty extreme warm air advection far into the Arctic, with over an inch of rainfall reported in <a href='http://i40.tinypic.com/15yjec6.png' class='bbc_url' title='External link' rel='external'>Spitsbergen, which is located at 77 degrees north.</a><br />
<br />
<span rel='lightbox'><img src='http://i44.tinypic.com/zlt9bt.gif' alt='Posted Image' class='bbc_img' /></span><br />

This strong high pressure is a consequence of a rather extreme block (+4 sigma!) currently over the the same region. This is literally what has been driving in the <a href='http://www.cpc.ncep.noaa.gov/products/precip/CWlink/daily_ao_index/ao.sprd2.gif' class='bbc_url' title='External link' rel='external'>AO to a rather strong negative value</a>.<br />

Since the strongest blocking has taken place over Europe, its no surprise to see that most of the cold will also be focused over Europe for the next week. The entire continent is expected to plunge into the ice box (yes even the Mediterranean vacation spots and all of Spain) over the next 3-5 days, with the 850 mb temperatures below 0 punctuating as far south as central Africa. <a href='http://i40.tinypic.com/e00uwi.gif' class='bbc_url' title='External link' rel='external'>This is 3-4 sigma below normal for this time of the year</a>, and will likely mean widespread frost to many areas that don't typically receive frost even in the heart of winter. In addition, a potent Mediterranean cyclone is expected to organize per the ECMWF and will likely cause snowfall to occur across the northern coast of Africa and deep into Italy and France.<br />

		<title>Petition to Prevent Budget Cuts to National Weather Service</title>
		<link>http://www.americanwx.com/bb/index.php/topic/32736-petition-to-prevent-budget-cuts-to-national-weather-service/</link>
		<description><![CDATA[(Someone from the NWS Employees Organization created this petition, not me)<br />
<br />
<span style='color: #333333'><span style='font-family: Arial, Helvetica, sans-serif'>"The passing of the proposed budget cuts for the NWS(National Weather Service)'s budget must not be allowed to happen, Allowing such budget cuts will not only cripple the NWS's ability(ies) to predict up and coming storms that has and will save many lives will put our nationals people back at risk of more unnecessary loss of lives. Further more a look at 2011's massive tornado outbreak, in April 2011 these tornadoes killed at least 344 people people in the Southeast, Midwest, and Northeast in just April alone. With the aid of radars, satellites and the employees that issued warnings of these storms saved many lives. I dare not think of the total losses that would have come if not for the NWS's warnings of these destructive storms."</span></span><br />
