The upper level low pressure system responsible for the past few days of rain will finally exit to the east of the region overnight. This will bring an end to the rainfall tonight. As the showers move out of the area, fog will quickly develop and likely become widespread during the overnight hours. Some dense fog will be possible, with visibility at or below half a mile. Conditions will improve Tuesday morning as a cold front slides south through the area.
Cool conditions will prevail through the first half of the week with temperatures near or just below seasonal normals. Much COLDER conditions are expected to arrive late Wednesday. Breezy north winds will ensure that temperatures fall to or near 32 degrees across much of North and Central TX Wednesday Night into Thursday morning. Strong north winds coupled with very cold conditions will result in wind chill values in the teens and twenties. Actual air temperatures on Thursday will struggle to climb above 40 degrees. Thursday night into Friday morning will prove to be even colder as clear skies and light winds are forecast. Overnight low temperatures during this time period will fall into the teens and lower 20s. This will likely result in some of the coldest conditions thus far this meteorological winter and likely some of the lowest temperatures this region has seen within the past two years.
