I hope this isn't another event where the precip just turns out to be freezing drizzle instead of light snow like the models indicate. Remember that happened a few years ago as well. Not fun.
It's been my major concern all afternoon and Jeff mentioned it in his afternoon briefing:
Hard Freeze warning in effect for tonight for all areas…including the coastal counties.
Band of light sleet/snow expected to develop and move across the region this evening between 600pm-midnight with a light dusting of accumulation possible.
Very cold conditions continue over the region today with College Station now on its 22 straight hour at or below freezing. BUSH IAH has only managed 33 this afternoon and as the sun sets expect the temperatures to fall quickly into the 20’s. Tail end of upper level short wave over TX appears to bring lift across the region this evening resulting in a band of mixed precipitation. While low level remain extremely dry, as experienced this morning, there appears to be enough moisture to allow light sleet/snow to reach the ground. The energy this evening may be a bit stronger than the episode this morning and a few quick bursts of moderate sleet/snow will be possible. With surface temperatures falling well below freezing this evening light accumulations will be possible especially on elevated surface which have now cooled close to or below freezing. This includes bridges and overpasses which can become slick as the initial sleet/snow melts and then refreezes into a thin layer of ice…as seen south of I-10 today over portions of Galveston and Brazoria Counties with the morning sleet. Will need to watch radar trends closely this evening for any enhancement of precipitation bands over the region. Radar is starting to show some echo enhancements near Austin which may be the start of this event.
Main item of concern tonight will be how cold will low temperatures fall. As skies clear after midnight and with the arctic surface high centered nearly over the region expect near excellent cooling conditions. Expect a damaging hard freeze for all areas with possible upper 10’s Walker, San Jacinto, Polk, Trinity, and Madison Counties. If skies are slower to clear then add about 2-5 degrees to most areas (or mid to upper 20’s).
Forecast Low Temperatures Wednesday Morning:
North of HWY 105: 18-22
North of US 59: 21-25
South of US 59: 24-28
