(KETK) - Tyler Tx — After 3 very warm days across East Texas, get ready for a strong cold front, a cold rain, and some wintry precipitation. What I will do in this blog post is to give you day-by-day details and what you can expect through this weekend.
Wednesday Night – Early Thursday Morning
Tonight, the cold front that we have been talking about will start its progression toward East Texas. So tonight, expect an increase in cloud cover across all of the area. An isolated shower cannot be ruled out tonight. What can be expected are the winds to begin their shift from the South/Southwest to the North/Northwest. Overnight, this wind shift will only impact along a line from Athens to Tyler to Atlanta—and this will mean temperatures tonight will be in the 60s and by early tomorrow morning in the 40s and 50s! Any areas south of this line, you will have quite a mild and muggy night. Your temperatures will be in the 60s and some areas of Deep East Texas will be in the 70s by daybreak.
Thursday will be a big transition day for East Texas. First off, we will have scattered showers during the day. The forecast models are not showing this day to be a washout, but coverage will be about 60% of the area. The bigger story for your Thursday will be the falling temperatures throughout the day. The image below on the left side shows temperatures in the upper 30s and 40s across East Texas for 12PM Thursday afternoon. The right side of this image shows temperatures at 6PM Thursday night. Notice how much of our area is in the 30s.
With much of our area in the 30s, you have to begin to wonder what kind of precipitation will occur. The best bet for a wintry precipitation from Thursday night into Friday morning will be from Tyler and areas Northwest. If you do not see the wintry precipitation, this will be a soaking, cold rain that you will be dealing with Thursday night into Friday.
From Friday morning through about late day, we will have showers that will persist across East Texas. Temperatures are expected to remain above freezing during the day. The shower activity will be a West to East progression and clearing out of our Western counties by the late afternoon and completely out of East Texas by late evening. So if you have plans for Friday Night Football, it’s going to be a very cold and blustery night. Make sure you are bundled up because with the North winds, wind chill values will be in the teens very easily.
Friday night, all precipitation will be out of our area and temperatures will drop below freezing. A concern that we will have is for black ice to form on roadways and side streets. So keep that in mind overnight Friday night into Saturday morning. Expect cloudy skies, and that will help keep temperatures from falling more than they could.
Saturday morning, temperatures will start just below freezing. During the day, we expect another round of light precipitation activity. However, this will likely fall as sleet or freezing rain.
Temperatures will slowly try to make it above freezing, but it will be difficult. With cold air already in place over our area, there will be a better chance of us receiving frozen precipitation in the form of freezing rain, sleet, or ice. This will happen during the day on Saturday and possibly into the overnight hours.
Who will likely see the wintry precipitation? During the day on Saturday, we believe all of East Texas is vulnerable to this. But during the evening and overnight, it will be confined to areas North of Tyler and Longview.
During the day on Sunday, our Northern counties will start out right at or below freezing. But as the day progresses, temperatures will warm right above freezing.
A wintry mix will occur during the morning hours in the Northern counties and a cold rain for Southern counties. We could have a brief heavy shower at times but all the precipitation will move out by Sunday evening.
This is a rapidly evolving weather situation and KETK is your source for the latest weather information. We will keep you updated, both on-air and online.
