Well, it wasn't easy but the back of this winter is finally broken. The colder air over New Hampshire was slow to erode Friday. But a cold front has cleared the coast, and drier and more pleasant seasonal air has arrived! Breezy WNW on Saturday will be active all day with gusts to 30 mph or greater. Highs will be seasonal for this time of year in the mid 50's. The day may start off with a little sunshine, but watch for building cumulus clouds from midday through afternoon which will make the skies look broken. Sunday will be the pick of the weekend. High Pressure will slide south of New England. Lighter, warmer west winds along with a more stable airmass (less cool air aloft) will make Sunday sunny and warmer with highs in the mid 60's.
An upper level ridge will hold on just long enough on the east coast to pump in another day of unseasonal warmth. Monday will be our day that we will have the best chance of reach 70 degrees! Weak front will approach early Tuesday morning, showers will be possible late Monday night and Tuesday morning. The showers will break down and cool us back down to near 60. Meanwhile, another high will follow behind to provide a few more days of sunshine and seasonally mild air. Needless to say, the ice will continue to this out, the snow snow will be melting. We will monitor the rivers for rises. Amazingly, not a single river is in flood across New England despite all the heavy snow of this winter. Thank goodness for that!
In the long range, plenty of questions regarding the end of the week set up, and also a turn to slight cooler temperatures. A deep trough will be digging towards the Gulf of Mexico by the end of the week. This will steer in heavy rain inot the southeast which will eventually be directed up the east coast and into New England. It is so far away it is silly to talk about timing, but our models do agree on the potential for a heavy rain event tapping into tropical mosture somewhere in the Friday to Saturday time period. As this low pulls away, it will play a role in dragging cooler air down in from Canada and bringing back some cooler into the pattern across the northeast.
