Let’s pretend yesterday did not happen. Let’s pretend it wasn’t in the 30’s with a 1/4″ inch of accumulating sleet for some. Would you be feeling better about this spring now that we have pretty much turned the corner? I know, the chill still remains from yesterday as well as the clouds with temps in the 30’s on Saturday morning. The good news is we will quickly be getting back on track this weekend as the sun gradually emerges and winds shift back in off the land instead of from the dreaded northeast direction off the water.

Low clouds are slow to depart this morning, especially at the coastline. A weak area of low pressure off the coast continues to pull away. Light northerly winds on the back side have been supplying the morning chill. Drier air moving in aloft is having some effect inland as clouds are breaking with partial sunshine inland. A gradual brightening to the sky should continue this afternoon with a mix of clouds and sun and highs in the Lwr-mid 50’s thanks to a light and warming WNW flow which is making all the difference in the world compared to the raw conditions of yesterday. Cooler temps in the 40’s to near 50 right at the coast thanks to lingering cloud cover..and possibly a light onshore wind developing in the afternoon.

A weak cold front will be pushing through tonight which will be the leading edge of another brief shot of cooler air which be moving in for Sunday through early Monday. This front will come with a few clouds and may even touch off a few spot showers or snow showers across the north country overnight. A few lingering clouds will be possible early Sunday with the proximity of the cold front pushing off the coast. Dry cool WNW winds will be breezy for Sunday with temps a bit cooler for Sunday with the cooler air moving in overhead. Skies will be partly cloudy with highs once again in the lwr-mid 50’s…seasonally cool for this time of year.

High barometer cool will be over us Sunday night-Monday morning, setting the stage for a cool and crisp start to Marathon Monday with temps in the mid 30’s at dawn, mid 40’s by 9 AM, mid 50’s by noon and upper 50’s for the afternoon with partly to Mostly sunny skies. High pressure will be pulling off the coast Monday so a light SE wind will settle in to cool the coast during the afternoon down to near 50 at the beaches and as the runners approach Copley square by 2 or 3 PM. It will be warmer inland away from the sea breeze. In summary, absolutely ideal weather for the runners compared to last year’s sweltering heat!

SW winds will be shifting in Tuesday with temperatures giving a run towards 70+ ahead of an approaching cold front. A big upper level ridge will be in place along the east coast allowing for this warmth to move from the Gulf all the way up to New England. This will likely be the pick ourdoor day of the week. A cold front will push inot the region on Wednesday. It will still be a very mild day near 70 or warmer in SNE ahead of the front, with clouds on the increase and a few late day showers. This front will stall over SNE by Thursday allowing for a cooler east wind wo settle in and temps dropping back inot the 50’s with cloudy skies. The stalled front will eventually work back north as a warm front later Thursday and open the door for another surge of warmth Friday where temps could again climbe to near 70-75 degrees under partly sunny, muggy and breezy SW winds. Another cold front will sweep through by Friday night inot early Saturday to bring the week’s steadiest rainfall.

After a week with temps likely trend above average, there are signs that a trough may try to return back to the Northeast in the April 22nd-to April 28th timeframe. This would likely lead to a cooler feel to end the month for much of the eastern half of the nation, and test the patience of those expecting warmth in a New England spring. Still, the Arctic Oscillation is turning Positive as well as the NAO…With less of a blocking pattern, a a flatter flow to develop, with less amplitude and hopefully more warmth in the pattern come may.
