Tonight’s lows should remain in the low to middle 40s, but it will be another cold night for East Texas.

TEMPERATURES REMAINING BELOW AVERAGE UNTIL WEEKEND

We are still under the influence of the upper air trough that brought severe storms across the eastern half of the United States. The unfortunate news is that our afternoon temperatures will remain about 2-3 degrees below normal for this time of the year. The good news is that we’re on the exiting end of this pattern. This means that an upper level ridge will setup over us, leading to warmer temperatures (80s) by this weekend.

Take a look at the graphic showing the height pattern at 18,000 feet. Right now, we are on the exiting end of this trough as it passes through the Deep South. Also note the ridging taking place in the western part of the country. This ridge will be moving over our area. This will keep us precipitation-free this weekend and very warm as well.

As we go into Sunday, the flow will be a west-to-east progression, meaning that warmer temperatures will begin to climb into the middle and upper 80s by Sunday. Our average high for this time of year is right at 80°.

HUMIDITY RETURNS BY EARLY NEXT WEEK

With this very warm air in place for the weekend, the humidity values will be low—meaning plenty of sunshine. By Monday and especially by Tuesday, the humidity and moisture will be returning—making it humid and muggy. We’ll have a few clouds on Monday, but Tuesday will be the day when we will likely have a partly cloudy sky with some cumulus clouds building in.

The increase in moisture and cloud cover means the upper level ridge will break down and will lead to rain chances by the latter part of next week.

CONCLUSION/SUMMARY

Here’s a summary of everything mentioned above.

  • Thursday morning was very cold. Another chilly night expected for East Texas for tonight/Friday morning.
  • Temperatures will remain cooler than average thanks to the upper air trough. But, by Sunday, a ridge will take place in the upper levels, meaning very warm temperatures and wall-to-wall sunshine.
  • That ridge will begin to break down by Tuesday, providing a muggy environment for East Texas and chances of rain by late next week.
