It is a cold and rainy Monday morning with temperatures around 40 degrees in most areas, setting up what will be a winter-like week across the ArkLaTex.
Pacific and Gulf moisture continues to get pulled into the region ahead of an upper level disturbance that will drive a cold front through later in the day. Widespread rain is expected through the morning, with heavy downpours at times. Through 7 a.m. we have flash flood warnings for Caddo, Bossier and DeSoto parishes where we have received several inches of rain since yesterday evening. Poor drainage areas, streets, creeks and bayous may take on high water. We may gradually see the heavier rain taper off as we move through the morning, but areas of scattered light to moderate showers will continue through the afternoon and into the evening.
It will be another one of those days with rain and clouds putting the brakes on temperatures. We are in the 30s and 40s this morning, and those are the same temperatures we see this afternoon. As a cold front moves through wind speeds will increase from 10 miles per hour this morning, to 15 to 20 miles per hour at times from noon until midnight. If you take temperatures in the low 40s, add a 15 mile per hour wind, you get wind chill temperatures in the low and mid 30s. Bundle up if you head outdoors!
Rain will gradually come to an end late tonight into tomorrow morning as an arctic airmass brings drier air into the region. As temperatures fall below freezing, we may still have enough moisture around to generate some winter precipitation across the northern ArkLaTex, but no accumulation is expected. Lows tonight will be in the 20s and low 30s. A Freeze Warning is in effect for most of east Texas.
We will see a gradual return of sunshine tomorrow but a breezy north wind and arctic air will hold our highs in the 40s.
A slow warming trend will carry us Wednesday through the weekend with highs in the 50s Wednesday and Thursday, and in the 60s Thursday through the weekend with very dry air keeping skies mostly clear to sunny.
Low temperatures will fall into the 20s across much of the region Tuesday and Wednesday night.
