Rain Expected Monday. Turning Much Colder Beginning Next Thursday - LCRA Rain Expected Monday. Turning Much Colder Beginning Next Thursday - LCRA


Here’s an update on weather conditions for this weekend, the first half of next week, and the arctic blast late next week.

This Afternoon through the Weekend

Quiet and cool weather is in place as we close out the workweek. A weak cold front is currently sinking south out of North Texas. The front is predicted to push through Central Texas by early afternoon, reach the Interstate 10 corridor in the mid to late afternoon, then finally move off the coast early this evening. There may be just enough moisture in place to squeeze out a few spotty light rain showers across parts of the middle Texas coastal region late this afternoon and evening. Rain amounts, if any, will only total a few hundredths of an inch. Widespread middle and high-level clouds will cause the sky to be mostly cloudy sky this afternoon and tonight.

  • Friday’s high temperatures will range from the low 50s north, the mid and upper 50s across Central Texas, to the mid-60s near the coast.
  • Lows Saturday morning will include the low 30s across the Hill Country, the mid and upper 30s across Central Texas, and the mid-40s near the coast.

Mostly sunny weather will be in place Saturday. Expect a mostly sunny to partly cloudy sky Sunday.

  • High temperatures will generally be in the mid-50s.
  • Lows Sunday morning  will include the low 30s across the Hill Country, the low and mid-30s across Central Texas, and the upper 30s near the coast.
  • High temperatures Sunday are forecast to be in the mid-50s.

Sunday Night through Monday Night

There will be an increasing chance for rain showers beginning after midnight Sunday night and continuing through Monday afternoon as a large trough of low pressure lifts northeast out of the Four Corners region. This system is expected to pull considerable moisture north from the Gulf of Mexico. The probability for rain will be 40 percent Sunday night, and 70-80 percent on Monday. The rain is forecast to end from west to east Monday afternoon into Monday evening. Totals through Monday evening are forecast to average less than 0.5 inches across the Hill Country, be between 0.5 and 0.75 inches  across Central Texas, and be around 1-1.5 inches across the coastal plains. Monday’s high temperature is forecast to be in the mid-50s. Lows Tuesday morning are forecast to be in the low and mid-40s.

Tuesday and Wednesday

A weak surge of cold, Canadian air is forecast to push south through our area Tuesday morning into Tuesday afternoon. Expect a mostly cloudy sky Tuesday, followed by mostly sunny conditions Wednesday.

  • High temperatures Tuesday will range from the upper 40s north, to the upper 50s near the coast.
  • Lows Wednesday morning are forecast to be in the low 30s across the Hill Country, the mid and upper 30s across Central Texas, and the low 40s near the coast.
  • High temperatures Wednesday are forecast to be in the upper 40s, with lower 50s towards the coast.
  • Lows Thursday morning are forecast to be in the upper 20s across the Hill Country, the low 30s across Central Texas, and the mid to upper 30s across the coastal plains.

Arctic Outbreak Arriving Thursday

An arctic cold front is predicted to push south across Texas late next Wednesday night into Thursday morning, bringing with it some very cold air! However, the exact intensity of this cold air is still somewhat in question. The arctic air is predicted to spill south through the Plains states next Tuesday into Wednesday, them barrel south across Texas beginning Wednesday night. Recent forecast model trends are showing a tendency for the core of the arctic air to move more toward Midwest and Great Lakes and not as much directly into Texas. If this works out, it will still turn quite cold, but not to the point of historic cold the solutions were showing earlier this week. Everyone should be preparing for at least a couple of nights with a hard freeze.

Based on the latest forecast data from Friday morning, here is a rough idea on temperatures to expect late week and into the holiday weekend:

  • Thursday’s high temperature will be in the upper 40s to low 50s.
  • Thursday night into Friday morning is shaping up to be the coldest of the week. Lows will include the mid and upper teens across the Hill Country, the lower 20s across Central Texas, and the low to mid-20s across the coastal plains.
  • High temperatures Friday are forecast to be in the mid-30s.
  • Low temperatures Saturday morning are forecast to be in the upper teens to 20 degrees across the Hill Country, the low and mid-20s across Central Texas, and mid to upper 20s across the coastal plains.
  • High temperatures Saturday are forecast to be around 40 degrees.
  • Lows Sunday morning are forecast to range from the mid-20s west, to the low 30s east.
  • High temperatures Christmas Day are forecast to be to be in the 40s.

I will caution that temperatures could trend colder than what I am presenting here—depending on whether the core of the arctic air moves directly into Texas, or more moves more to the east of us. Stay tuned for more updates.

Forecasts show generally dry weather late next week through Christmas weekend.

The outlook for the week after Christmas shows milder temperatures, with lows in the 30s ad 40s, and highs in the 50s.

Have a good weekend.
