Weekend winter storm update 11:00 PM

0z American models are in. The NAM and GFS are actually in pretty decent agreement right now, especially in regards to the triangle. Both models are showing about 1.25ish inches of liquid precip for the Triangle... most of which will fall as snow with possible snow pellets and sleet mixed in. The timing and precip intensity could still change. Still feel very confident that whatever falls will be frozen.. whether it be ice or snow. The 2 big questions from this storm are 1) will it be ice or snow? and 2) how much precip will we get. Subtle changes can lead to different results in regards to both of these question.

Now.. with the above caution in mind... taken literally these two models show snow amounts of around a foot for the triangle. Could be more or less depending on how much sleet is present.


Friday afternoon - 30% chance of afternoon snow - High near 40

Friday night - Snow... possibly mixed with sleet - Low near 27

Saturday - Snow tapering off to flurries in the evening. High near 29

Saturday night - Flurries before midnight and then clouds decreasing . Low near 19

Total accumulation of 9-15 inches possible.

Will update after the 12z data is in... sometime tomorrow afternoon/evening.
