Our mild weather continues today into tomorrow morning until a sharp cold front moves across the area which will drop temps during the day tomorrow down into the 20's by late tomorrow night into Saturday morning. We will also see some much needed rain as we have only seen 0.09" of rain on just 2 days this month. We are almost 2" below normal this month. I have heard reports that Marsh Creek Lake is as low as folks have seen it in a long time. The combined lack of snow and rain is taking it's toll. The good news is we could see between 0.50" and 0.75" across Chester County between showers today and then more rain associated with the cold front tomorrow morning. Records for today: High 72 degrees (1954) / Low 2.8 below zero (2015) / 14.7" (2003) as part of the PD2 Blizzard of 2003 when we received 21.3" of snow - this was the 5th largest February snowstorm in Chester County history. Happy Pitchers and Catchers reporting Day for those who celebrate!!!

Of course....they can't produce an actual disaster verification or prediction except what a model tells them how disastrous the world will be in 200 years.....

Except the statistical analysis proves there is no bias or by chance relationships between the various data sets and observations in the data. If there was the statistical p-value in the data would not have delivered the level of significance against the null hypothesis. It's simple scientific data testing and analysis.

Of course as the actual real world data is not aligned with the popular global story....I get it

Thank you! Agreed the fact that some have been convinced that this is a crisis and that young children like mine rank climate change as a threat to their future is ludicrous. Apparently they are concerned about bringing children into the world due to this so called "climate disaster" is pure unadulterated lunacy!! Even if we warm by 1 degree (a big assumption) in their lifetime by 2100 their life will not significantly change for them or their children. The fact anyone with dissenting opinions on any topic is silenced or derided is sad. Science must always be questioned!!

Why the insults again...thanks for allowing me to figure out the impacts of ocean warming and related energy!! LOL!!!!! Of course Charlie no prediction or forecast is "laughable" until we have verification....let's chat in the late 2030's and 2040's.....

LOL! actually make those thermometers/stations plural so thermometers in Chester County PA!!!

Thanks dseagull! great to have some diversity of thought and opinions on this topic!!

Could see a shower this AM with a warm front with sun returning this PM with temps warming to the low 60's in many spots. Rain by tomorrow afternoon and then sharply but briefly colder by Friday afternoon into Saturday. Records for today: High 75 (1949) / Low 11 below zero (1899) / Precipitation 1.61" (1987) / Snow 13.0" (1958)

Ocean of course cools and warms at a much different pace than land....I only address land temps for Chester County PA....

Below is March average temps since 1894 through last year. Cyclical of course but overall flat to a slight decline

I will look at March individually across only Chester County but for the March - April - May spring months overall as usual any actual temperature changes appear cyclical. With overall Phoenixville warmer - West Chester flat and Coatesville trending cooler

At least for the area analyzed below - based on the clear cycles of warm - cold illustrated below I would expect we see the trend downward starting later this decade....

Another well above normal day today with temps in the low 50's. Our normal high today is just shy of 40 degrees. Of note today is the last day in the winter with average high temperatures of less than 40 degrees. The next time average high temperatures are in the 30's will be December 19th. Tomorrow we will approach near 60 but with increasing clouds. Rain looks to arrive on Thursday into early Friday. Will will turn briefly chillier again on Friday PM into Saturday before warming up again by Sunday. Our records for today: High 63 degrees (1949) / Low 4 below zero (1979) / Precipitation 1.25" (2007) / Snow 10.0" (1899)

We picked up a needed .07" of rain yesterday. Beautiful late winter day across the County today. Temps today in the 50's and we might hit 60 degrees on Wednesday. Looks like rain again by Thursday. The record high for today is 65 degrees from 1951. Record low was the 5 below zero from 1979. The daily precipitation and snow record are both from today's date in 1899. In the midst of the greatest snowstorm in Chester County history with 35.3" of snow falling on the 13th alone and an incredible storm total of 53.0" by the time the storm wrapped up on Valentines Day.

We have now exceeded 120" of accumulated GFS Snow model snow this year for Chester County....only problem is no winter event this season has even hit the 1 mark.....

Hi Charlie....the supporting information is the raw data above - it is right there on the page - I even posted the ranking that clearly show the 1930's and 1940's are the warmest decades. Now of course I understand with the "bias adjustment" applied to the data it supports the warming much better....but we like our weather like our onions....raw!! Go Birds!!!

That well respected MET JB says for the Period March 1 through April 15 - PHL is 5 degrees below normal with 15" of snow.....this will not age well

Cloudy and chilly today with the best chance of rain across SE Chester County with less chances the further NW you travel across the county. Temperatures then warm up through Friday with highs possibly touching 60 degrees by Thursday. That day is also the best chance of rain after today. Much cooler again by Friday night into next weekend. Records for today: High 68 degrees (1999) / Low 1 below zero (1979) / Precipitation 1.46" (1985)/ Snow 12.8" (2006) - GO BIRDS!!!

Of course Tip...but the actual unadjusted data should follow suit...there should be consistent data without adjustment for the 1930's and 1940's that support this supposition....correct?? How can we find entire counties in the USA that do not follow the same warming we should expect to see?

But of course the unadjusted data for all of the available Chester County sites does not show the above trend lines.....
