Winter Weather Advisory Tonight Sleet Freezing Rain Snow Into Sunday Morning
Winter Weather Advisories have been expanded to include areas from South Central and Southeastern Pennsylvania, most of New Jersey except the northwest corner, the lower Hudson Valley, NYC, Long Island and Southern Connecticut.
We aren’t talking about a lot precipitation here. In fact the precipitation will be light from this weather system and rather uneven. Nonetheless all it takes is a few hundredths of an inch of precipitation to create a glaze on roadways tonight into Sunday morning. That will mean hazardous driving conditions overnight.
Snow is not an issue with this system. While the air is cold at the surface there is a warm layer at around 5000 feet where temperatures are above freezing, melting the snow on the way down and either it falls as freezing rain or freezing drizzle, or it falls as sleet.
The radar shows precipitation advancing slowly northeastward but it is mostly on the light side. In areas on the northern flank, the air is so dry that it is evaporating before it reaches the ground.
Precipitation will be spotty by Sunday morning but there still could be some freezing drizzle around from time to time. Temperatures tonight will hold in the 20s and only slowly rise to the upper 20s to lower 30s on Sunday. Some areas could see temperatures poke their noses above 32 with cloudy skies all day long.
Monday will be a cloudy cold day with highs in the upper 20s to mid 30s. The next storm system will be pulling up just enough warm air to change any sleet or freezing rain Monday night at the start to rain at the coast. Inland however freezing rain could last a while into Tuesday morning before the storm exits. Wednesday looks dry and cold before another storm heads our way Thursday. This storm could produce a front end thump of snow before it changes to rain. We will have more on these two systems tomorrow once our weak overnight system is done.
