Sunglasses today, Umbrellas again Thursday

PROVIDENCE, R.I. (WLNE) — Our major Nor’Easter that mostly missed us is weakening today and spinning through the Canadian Maritimes. It did give some areas of eastern MA and NH and ME some snowfall. Our ground is not frozen, so the snow melts from below too!

Map

Our focus now is on a system to our west that will weaken as it moves in today. High pressure delivering sunshine this morning, but clouds will return this afternoon with the chance for evening sprinkles.

The next storm approaches Thursday with a warm front bringing us a steady rain Thursday afternoon and night. This ends Friday morning as a mix of rain and snow or a change to snow showers.  No arctic air or major snow event through the weekend.

Our 18 hour rainfall will approach an inch by sunrise Friday.

La Nina (opposite of El Nino and one of the reasons for our mild, snow-less winter) occurs periodically. This year it’s back.

La Nina 1

Much like upwelling at our shoreline, the cooler water just below the surface rises when the warm surface water is pushed away by the trade winds. At our Rhode Island beaches, when there’s a land breeze, the same effect happens on a smaller scale. Warmer gulf stream waters are pushed away from the shoreline and cooler water at greater depths along the continental shelf rise to the surface.

La Nina 2

Those fast winds at about 5 miles up govern our weather pattern and this is pretty close to what we’ve had this winter so far. We’ll have to see whether La Nina conditions wane in February and March. If they do, that pattern may turn more wintry than spring-like.

No arctic air is in the forecast this week and at that point, January, our normally coldest month, is just about done. There is an indication that winter cold and the chance for snow may be in the offing  after next weekend as we prepare to welcome February.
