A wet morning can be expected on this Tuesday with showers spreading west to east across the state. The rain will not be very heavy, with only about a .25-.50" of rain expected to fall, but it will be a steady rainfall from about 7 AM through 11 AM. The showers will be tapering off by midday as a cold front will push off the coast by early afternoon. Dry westerly winds will follow in behind the front with breaking afternoon sunshine inland with highs in the Lwr-mid 50's Clouds will hanging tough at the coast for most of the day. Showers may linger at the beaches through early afternoon. The sunshine will increase from west to east during the afternoon. By 4-5 PM...most of New Hampshire should be sitting in the sun for a nice evening ride home.
High pressure will be sliding from the Great Lakes towards the Northeast for the midweek providing for beautiful dry pleasant spring weather with highs in the 50's. A perfectly seasonal airmass. As the high shifts farther north into Canada it will begin to wrap in a cooler NE wind at the surface. Winds off the 42 degree water can make the coast line be quite a bit cooler, than from the milder temperatures inland. That will be the case this week. Everyone will bask in the sunshine, but the beaches will struggle to warm with highs remaining in the 40's and Lwr 50's, while inland highs will be in the 50's to near 60.
Overall, there is more blocking in the atmosphere than we have seen in awhile. Sometimes, if you are on the more unfavorable side of the block, inclement unsettled weather can last for days. If you are lucky enough to be on the good side of the block, it will mean days of sunshine. That is exactly where we are heading! A huge upper level ridge will be building over the northeast as we approach the weekend. This will provide more sunshine and temperatures will be climbing into the 60's and even Lwr 70's!
Of course, with this pattern, back door cold fronts can be very typical and can quickly shut down the warmth with a simple windshift to the Northeast. That may happen to start next week sometime. The timing of the backdoor front will change, but it does appear some of the warmth of the weekend may be in jeopardy heading into the start of next week. Nothing automatic that far out in the game. For now, it is morning showers Tuesday, and then tons of sunshine and pleasant weather ahead. It's all you really need to know right about now!
