A Rapid warm up for Easter Sunday!Temps were frosty cool at sunrise with most areas outside the city in the 20’s. Now with sun, and SW winds temps will be quickly soaring into the 50’s to near 60 this afternoon. High clouds will be increasing this afternoon and thickening ahead of a batch of rain which will be pushing through tonight,,,mainly after 8 PM. The rain will be short lived, with about a quarter inch rain to fall, and will tapering to showers and winding down after midnight.

Monday will see a fair amount of sunshine with a breezy WSW wind. With temps starting in the 40’s, it will not take much to see temps quickly climb back up to near 60 degrees by Monday afternoon. Another cold front will approach late in the day. This will be the leading edge of the colder air pushing from Canada to The Great Lakes and into New England. This front may trigger a late day shower before sunset Monday.

Breezy NW winds will usher in much colder air Tuesday through Wednesday with a trough pushing through the Northeast. This should the final blast of winter-like air before we start to turn this spring pattern around in a big way. It is safe to say that I think we are finished with our snow storms. The midweek will be filled with sunshine, but highs will be about 40-45 degrees with wind chills feeling in the 30’s. The coldest air will be felt once the sun goes down in the early morning hours before sunrise. Lows will drop into the mid 20’s..so will still have the winter coats for the kids heading out te door to school. Temps will slowly begin to moderate into the Lwr-mid 50’s by Friday.

We will have to watch the coast for the end of the week. A storm currently moving onshore to the California coast is the next potential weather maker we will have to watch. The Greenland block is still in place and is one of the reasons we are getting this next cold shot of air. The block is also another reason why this Pacific low should be steered south stay far enough away from us for any big effects. Still it will need to be watched as recent models have this trending a bit closer to us. This low dive south from California towards the Gulf of Mexico, and accumulate a more significant moisture source. It will then track towards the Carolinas then off the coast. The track off the coast is to the northeast, so there is a potential that this low will track near the bench mark where we could start to see some fringe effects from this low..Showers are possible by Friday night and may even mix with snow showers by dawn Saturday morning across eastern MA. It won’t last long. Dry cool seasonal air will quickly follow in behind the departing low for next weekend. It is all very early..and there will be more gradual changes in the days to come as we will get a better handle if the block will hold or weaken…which would open the door for more precipitation from this coastal low.

With The Arctic Oscillation trending positive, the NAO trending Neutral signs are showing for a big shift in the over all blocking pattern which has dominated our weather for the past 2 months. With a trough finally lifting out, more upper level ridging should begin to become established on the east coast heading farther into to April. There are plenty of warm signals in the very near future…and not much cold left in the tank. One more week to go and we will be going full speed into spring!
