7PM Tuesday

First winter storm of the season continues to be forecast for Thursday into Friday. Cold air will be in place over the region on Thursday with high temperatures just making it to the lower 30s. Developing storm system will move in from the south Thursday afternoon with snow now expected to develop during the late afternoon or early evening. Snow is likely to continue through at least 12AM Friday with much of the accumulations likely occurring during this timeframe. After midnight, snow is increasingly likely to mix with and change over to sleet. While sleet still has many of the icy properties of snow, it simply does not accumulate as well, so there may be a leveling off of the accumulation amounts after midnight. Liquid rain is likely to begin mixing in sometime after 4am and gradually taper off through the morning. Key factors that will determine exact accumulation totals and impacts are 1) how heavily snow falls Thursday evening, and 2) how long the transition from sleet to rain takes Friday morning. Today, there has been a slight trend toward heavier precipitation Thursday evening, resulting in the potential for moderate to heavy accumulations. This has been acknowledged in the "extreme range", however the "likely range" remains more conservative at this time.


Based on the current trends, it is likely that the National Weather Service will issue a winter weather alert sometime on Wednesday. For a refresher on what different alerts mean, check out today's Facebook post on "Understanding winter weather alerts": Link!

6PM Monday

The first of two storms this week will bring rain from about 12AM tonight through tomorrow morning. No snow/sleet accumulation. Attention instantly turns to second storm for Thursday-Friday. Since this morning, there really hasn't been much change, but rather an increase in confidence of the previous forecast. Cold air in place over the region on Thursday (temperatures in the 30s), will set the stage for a potential snow event. A storm will approach from the south with precipitation likely overspreading the area Thursday evening. Precipitation is likely to start as or quickly change to snow. As the storm progresses, it will gradually erode the cold air changing snow over to sleet then eventually rain on Friday. Snow/Sleet amounts will be very dependent on how long it takes to erode the cold air, but it is possible that it could take most of the night. With plenty of moisture to work with, the potential exists for several inches of accumulation.


With the storm still being three days away, there is certainly the potential for the snow gauge to shift. The ranges are expected to eventually narrow down and a specific forecast will be issued as confidence increases.

Tuesday Evening


12AM Monday

The average date of Kingston's first snow is November 30th, meaning that half of all winters see snow before then. Two storms will roll through the region this week. With increasingly cold air moving over the region, there is the potential for some wet snow or frozen precipitation at the onset of the second storm.

Today we'll see generally clear and calm conditions as a storm system develops well to our south over Texas. Tonight the storm will move up the coast bringing rain after midnight. Temperatures will be in the mid to upper 30s as the precipitation begins, so it is possible that some sleet may fall with the rain. However, if sleet does mix in it will be too warm for it to accumulate. Additionally, as the storm progresses, it will erode cold air above the ground changing any sleet over to plain rain. Rain should taper off by Tuesday afternoon. Behind the storm colder air will filter into the region for Wednesday and Thursday. We'll see intervals of sun and clouds Wednesday and Thursday as high temperatures fall into the 30s; low temperatures will dip into the 20s. This cold air will set the stage for potential snow Thursday night as a second storm moves in. The storm will be very similar to tonight's, but with colder air in place it is likely to begin as wet snow Thursday night. Best chance of snow will be after sunset Thursday. A gradual transition from snow to sleet to rain is likely Thursday night into Friday morning. This storm will need to be monitored this week, but there is currently the potential for light snow accumulation.
