1/21 – Rob Knight’s “Winter Weather” Friday Morning Forecast
Light freezing rain/drizzle this morning will move east and transition back to liquid by mid-morning. A WINTER WEATHER ADVISORY is in effect through noon.
A deep layer northwest flow pattern will persist through Sunday, this will allow for continued cold air advection into the region. The wind field will also weaken as surface ridging becomes more centered over the area, and a couple of nights of strong radiational cooling are expected both Friday and Saturday night. Temperatures could drop into the lower to middle 20s for areas along and north of I-10/12 and the upper 20s and lower 30s south of this corridor. Hard freeze and freeze products will likely be issued for the weekend. Temperatures will also run below average through Sunday. Highs will only warm into the lower to mid-40s on Friday, but will gradually modify into the lower to middle 50s by Sunday. Overnight lows Sunday night will cool into the upper 20s and lower to middle 30s, but a hard freeze is currently not forecast.
A fast moving and vigorous southern disturbance will slide into Texas on Monday. A region of favorable lift over the western Gulf will allow for intensification. This low-pressure will rapidly deepen as it moves to the east-northeast, and it should pass through the forecast area Monday into Monday night. Fortunately, temperatures will warm significantly in advance of the low, and only rain is forecast as the system moves through next week. Lows should climb into the 40s as the system moves through Monday night and highs should be in the upper 50s and lower 60s.
