A light Snow Accumulation This Afternoon

 

PROVIDENCE, R.I. (WLNE) — As our storm system moves over us today, expect light rain to become moderate again late this morning and then mix with and change to snow. Expect a coating to an inch for the northern half of the ocean state. Near the MA border, 1 to 2 inches could accumulate between noon and 6pm.

Clearing sky and temperatures in the 20s will help develop some icy pavement. Wind chill will dip into the lower 20s at times.

No arctic air or major snow event through early next week however, a colder pattern and a favorable storm track for snow may evolve by late next week.

This pattern will be with us mid to late week next week. It’s an interesting storm track. Someone in New England will get a decent snowfall!

The Wednesday storm track right now looks wet for Rhode Island with more snow interior and northern New England. We’ll track any changes to that track as a slight shift could mean more or less snow for us.

A slight shift (100 miles or so) to the southeast in the storm track would be just enough to give us an appreciable snowfall, but this does not appear to be in the cards.

It wouldn’t take much in a shift of the storm track for the Rain-Snow line to set up over southern Rhode Island. This would keep some of us cold enough for a wet pasty snowfall.

WHY THE MILD, SNOW-LESS WINTER?

A BIG INFLUENCE IS OCEAN TEMPERATURES IN THE PACIFIC.

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.

January, our normally coldest month, is just about done and it will go on record as a warm one. There is an indication that winter cold and the chance for snow may be in the offing for the last weekend of the month and prepare to welcome February.
