(KETK) - Tyler, Tx — Wednesday was our day of transition from the cooler airmass to a warmer airmass. We started Wednesday morning with temperatures in the upper 30s and lower 40s. But highs yesterday rebounded very nicely into the middle/upper 70s with a few 80 degree readings.
Today, a much different story! Lows this morning were in the upper 40s and lower 50s. Highs today reached the upper 70s and low 80s across the area. It was also a very windy day with dew points beginning to rise. More moisture and high clouds are being brought into East Texas because of the strong southerly winds.
In this blog post, we’ll talk about what you can expect for tonight, Friday, and Saturday. I will also give you a preview of what we are looking at on Sunday—that is when we could see some strong storms.
THURSDAY NIGHT & FRIDAY MORNING
This evening will be very mild and breezy at times for East Texas. Temperatures in the early evening hours will be in the 70s and by late evening to the upper 60s and low 70s. We could see a few high clouds roll in by this evening, but they will be more likely in the overnight hours. By daybreak Friday, lows will be in the upper 50s to low 60s.
Here are the GFS & NAM models for temperatures at 7PM tonight and 7AM Friday morning.
For your Friday, you can expect clouds to be on the increase for East Texas. Those clouds moving in will equate to more humid and warmer conditions. Winds will not be as strong as Thursday, but highs will be in the upper 70s to low/middle 80s.
Below are the GFS & NAM temperatures for 1PM on Friday, as well as dew point values for the same time.
Friday will be a nice day, but partly to mostly cloudy and humid. The evening hours will be very mild and by daybreak Saturday morning, I believe we will be mainly in the low 60s with a few locations in the upper 50s.
A tighter pressure gradient will mean a windy Saturday for us. Windy conditions will also usher in more clouds—providing a mainly cloudy Saturday. Despite the clouds, temperatures will remain very warm with highs mainly in the low to middle 80s for the area.
The NAM model is showing some spotty showers during the afternoon hours on Saturday. An isolated shower or sprinkle is not out of the question, but KETK Meteorologists are not expecting much rain because there is no upper-level forcing mechanism to set off precipitation.
Saturday will be very muggy. Dew point values will be in the middle 60s.
Sunday is a day we are watching closely. The latest computer model data suggest showers and strong to severe storms will be likely especially by afternoon and evening. Below is the GFS and NAM precipitation output for Sunday at 7PM.
The European model agrees with an afternoon and evening storm threat.
Supercell storms—storms containing very strong rotating updrafts and downdrafts to produce very heavy rain, hail, and possible tornadoes—will be likely Sunday ahead of a cold front that will sweep through the area.
Because of this threat, the Storm Prediction Center has portions of East Texas already under a Day 4 (Sunday) risk of storms. As we get closer to the event, this forecast will become more specific on when and where the storms will likely form.
By Monday, much cooler air will move into our region with well below normal temperatures.
