Pretty impressive to see the NAM wind gust guidance come in at 70 mph or higher.

Good model agreement on a near record April LLJ for Monday. Short term meso models should provide guidance on how much convection is able to develop. Stronger convection would mix down a portion of these winds from aloft. https://forecast.weather.gov/product.php?site=NWS&issuedby=BOX&product=AFD&format=CI&version=1&glossary=1&highlight=off By 18Z Monday guidance shows a southerly 850 mb LLJ of 90-100kts! GEFS ensemble guidance shows v (southerly) component of the jet at 5-6 standard deviations above normal.

Portions of Maine set a new April low pressure record.

Just had a few snowflakes here in SW Suffolk.

Interior portions of the area could see a wet snow squall tonight. Midlevel lapse rates will be near record levels for April.

Some of the highest gusts reported right along the Jersey Shore.

The -NAO/-EPO limited the maximum temperature potential. So the high temperature couldn’t make it to 80 like other recent years. But the -PNA and warming climate gave us the warm departure.

Near record April low moving through the Northeast next several days. It will snow over higher elevation and far enough north regions. Our area could see strong storms tomorrow followed by a freeze in the usually colder spots this weekend.

Made it to 63 degrees before the sea breeze arrived.

I hope that you get better soon.

The -EPO takes over once the -NAO weakens. So we get a trough in the Great Lakes and Northeast. The MJO VP anomalies support this general pattern.

Yeah, the MJO supports a trough in the Great Lakes and Northeast around that time.

Good to see the sun come out with temperatures near 60 this afternoon.

It’s been the pattern since 2012 to get a big spring -NAO drop following a +NAO winter. 2012 1.17 0.42 1.27 0.47 -0.91 2013 0.35 -0.45 -1.61 0.69 0.57 2014 0.29 1.34 0.80 0.31 -0.92 2015 1.79 1.32 1.45 0.73 0.15 2016 0.12 1.58 0.73 0.38 -0.77 2017 0.48 1.00 0.74 1.73 -1.91 2018 1.44 1.58 -0.93 1.24 2.12 2019 0.59 0.29 1.23 0.47 -2.62 2020 1.34

Getting some breaks of sun between the rain bands moving through.

All-time record high pressure at1070 mb in Northern Canada today.

Winds coming in above guidance with the big offshore storm. Looks like we get some rain on Friday as the storm loops back toward the coast. Kennedy Intl FAIR 48 31 51 NW29G40 29

We are getting our strong spring -NAO pattern. This has been a common feature in recent years following the record winter +AO./+NAO. Records for high pressure have been set over Northern Canada.

The cutter, hugger, and suppressed southern stream storm tracks have dominated last few years.

Yeah, the warm sun felt nice today. The ocean storm to our SE is beginning to take on some subtropical characteristics. Looks like it will be pretty windy the next few days especially out toward Eastern LI and Cape Cod.

Getting more sun today than yesterday. Strong ocean storm is moving SE of the area under the big -NAO block.

Yeah, we can see above normal summer temperatures during a -NAO. It looks like parts of Northern Canada could approach record high pressures this week with the -NAO. Models have been showing high pressure getting above 1060 MB this week.

Very Impressive +5SD block near Greenland. Typical spring -NAO temperature pattern. Cool inshore flow here with 80’s over the Mid-Atlantic.

High temperatures usually beat guidance on these dry and sunny downslope flow days. Newark Liberty FAIR 68 26 20 NW12
