Delayed Warmth...
We had a taste of warmth yesterday with highs reaching into the 70s for Easter Sunday but since then, high pressure has been strengthening to our north changing our wind direction and pushing cooler maritime air back into Eastern New England. This battle between airmasses will be ongoing for much of the week...eventually the warmth will win out but it will take some time.
Low clouds, fog and cool temps will be locked in tomorrow too thanks to the high to our north and a weak wave of low pressure sliding through our coastal waters that will reinforce the onshore flow so temps will stay near 50 for most of the region tomorrow. The front from a line near Rhode Island to Worcester County to near the NH/VT border this means that Western NE will still be rather warm and muggy while most of us stay cool and clammy.
The high locking in the chill will begin to retreat Tuesday night allowing the warmer air to work back to the north and strong SW winds will transport 70s into most Eastern Mass with 80 attainable in Central and Western MA...SE areas will stay in the 60s and even 50s on the Cape.
Thursday will also be a warm and muggy day but a coldfront will sweep in late in the day with showers and possible T-storms for the evening. Most importantly, it will usher in a drier airmass with more sunshine for the end of the week and the start of the upcoming weekend.
