Forecast discussion: A weak high pressure ridge brought dry weather to Providence for most of Sunday. However, the high will give way to a low pressure system over western Pennsylvania. This low will bring some light to moderate snow showers by this evening. Any moderate snow bands will occur between 10 p.m. and 2 a.m. All snow showers will come to an end before the start of the morning commute on Monday. I’m only expecting a coating to 2 inches, with the highest amounts along the south coast.
We will see sunshine slowly work its way out of the clouds by Monday afternoon. However, a deep upper level trough will bring Arctic air back over the region, starting Monday night. Overnight lows will be in the lower teens Monday and Tuesday evening. High temperatures will only make it to the middle 20’s for Tuesday and Wednesday. Increasing clouds Wednesday night will blanket us, keeping some of the sun’s energy from leaving the atmosphere. Temperatures will only fall to the upper teens.
The computer models have been having a hard time coming to a basic agreement about the next storm system. A low pressure system will begin to develop in the eastern Gulf of Mexico, and then follow along the eastern coastline. The track if the low is the most important aspect. At this time, with the exception of the American model, the low stays offshore and to our east. This means we would stay in the colder part of the low. This means we would see some decent snowfall Thursday into early Friday morning. However, the American model puts the low’s center further to the west. So, we would start off as snow then change to a wintry mix, before changing over to rain. At this time, my confidence level still remains low. The low’s track changing even 30 miles either way greatly changes the precipitation type, and therefore the snowfall amounts.
The models do agree that any snow showers will end by early Friday morning. A high pressure system slowly moves over the Mid-Atlantic and gives us dry weather for next weekend. Temperatures will be seasonable during the day, although Saturday night’s low temperatures are slightly below normal for the middle of February.
