*Summerlike Warmth Breaks Many Northeast Record Highs
From AccuWeather News
With temperatures soaring into the 80s and even 90s across the Northeast, Wednesday felt more like summer than early April. Numerous record highs were set, and some places experienced their earliest 90-degree temperature reading.
A southwesterly flow of air pumped the unseasonable warmth into the Northeast on Wednesday. Temperatures exceeded typical early April highs by 25 to 35 degrees.
Over two dozen of the major reporting sites in the Northeast set record highs on Wednesday. A sampling of these are given below with the old record in parenthesis.

Record Heat across the Northeast US

Release of the Atlantic Hurricane Season Forecast by CSU

Scotland enjoys milder temperatures in a typical unsettled April pattern

Record Heat across Northeast US and potential for Severe Thunderstorms later today!

Wednesday was more like July 7th rather than April 7th as temperatures rose past old records with ease aboard a strong heat pump of southwest winds and a strong upper level ridge pattern across the Eastern third of the nation. This was in contrast with continuous snows out West over the Rockies and cold temperatures which supported snows down across Salt Lake City.. The western trough and eastern ridge is what’s creating the contrast in temperature but this entire pattern is migrating east and the cold and snow out West will head towards the east dropping temperatures 20-40 degrees within a 48-hour time frame over the next couple of days. Philly, NYC and Boston may struggle to top 60 to 65 degrees by the weekend after summerlike 90s.

This type of pattern is progressive and we will see a front slide eastwards through Thursday evening and may spark severe weather across the Ohio Valley and towards the coastal plain of the Mid-Atlantic (general area between the Appalachain Mountains and the Atlantic coast) and up into the heavily populated corridor from DC to Boston. A box generally from State College, Pa down to Arlington, Va and across to the Delmarva and up to Boston will see a round of thunderstorms later today (Thursday) as a storm system now spreading snows across the upper Great Lakes will spread a front ahead of the low towards the East Coast but the timing of the front with daytime heating will be the major factor in whether we see “severe thunderstorms” blow up with intense daytime surface warming which would enhance the instability of the atmosphere and could fire stronger thunderstorms along the frontal system as it pushes towards the Eastern Seaboard. Nighttime tends to see the cooling down and therefore demise of the “bubbling up” factor created by strong surface heating which sparks dynamical instability and brings intensifying thunderstorms which can bring enhanced downpours, fierce lightening, hail, damaging winds and even the chance of a tornado.

This is very much like a mid-summer set up, not early April for the Northeast US where it could just as easily be in the 40s or 50s with a cold rain or even snow.. This weather will break down, good news to non-heat lovers and those who are saying, this kinda weather is way too early.

Here is a selection of the major records set yesterday from AccuWeather.com

–New York City’s Central Park: 92° (89° from 1929)
–Providence, R.I.: 92° (86° from 1991)
–Atlantic City, N.J.: 91° (84° from 1991)
–Washington, D.C.’s Dulles Airport: 91° (84° from 1991)
–Boston, Mass.: 90° (86° from 1991)
–Trenton, N.J.: 89° (88° from 1929)
–Portland, Maine: 85° (78° from 1991)
–Bridgeport, Conn.: 81° (73° from 1997)


Colorado State University releases their Atlantic Hurricane Forecast 2010

A similar overall forecast idea to Joe Bastardi of AccuWeather.com and this is more worrying when you see individual forecasts coming out with a similar idea… This should be a very interesting hurricane season.

Scotland endures milder temperatures but within a typical unsettled April Pattern

Today felt “almost warm feeling”, but it has been very unsettled with on and off showers, some heavy and then we enjoy periods of sunshine, some long periods. This is typical of April and the ever so slight rise in temperatures towards comfortable levels will be nice and pleasant, despite the showers, the weather could be a lot worse, afterall we could still have snow and ALSO it wcould be a whole lot wetter than it is… It can only get better we we appraoch the middle of April… Remember, April showers bring May Flowers!

What’s Reaching Today’s Blogs?

Over 1,000 Heat Records Broken in Northeast
From Jesse Ferrell, AccuWeather.com
UPDATE Thursday 4/8/10: With yesterday’s records added in, the totals are 857 Record Highs Broken with 401 Record High Minimums, for a total of 1,258 records broken. What caused this? Basically a blocking pattern setup and kept warm air moving in our direction for about a week. Today’s front will “unclog” the system.
I blogged Monday about the record heat wave sweeping the Northeast quadrant of the country. Today I can update those stats… we now have (up to yesterday) 671 record highs broken this month (plus another 293 record high minimums, for a total near 1,000).
