Ready the rain gear…again
PROVIDENCE, R.I. (WLNE) — A small area of high pressure will slide over us tonight delivering some partial clearing, but the clouds return in earnest on Thursday morning. The next storm for us now over the southern and central plains will move northeastward tracking west of us once again by Thursday night. This keeps us on the milder side of the storm. Rain will begin mid afternoon Thursday and become heavy after the evening commute.
As a secondary low pressure develops over Long Island, Rain will likely change to snow over Worcester County late Thursday night. We will see our heaviest rain between 8 pm and 2 am.
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.
In about 15 hours, we’ll receive near an inch of rain before sunrise Friday.
TODAY: Sun and clouds. Highs near 50°!
TONIGHT: Partial Clearing. Lows near 32.
THURSDAY: Morning sun to midday clouds. Afternoon rain developing 2 to 4 pm. Highs in the 40s
THURSDAY NIGHT: A soaker. Steady Temperatures 35 – 40.
FRIDAY: Midday snow showers. Highs in the 30s.
WEEKEND: Mainly dry and seasonal, Near 40°.
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.
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.
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.
