The ERCOT Weather Forecast is developed by ERCOT Meteorologists Chris Coleman, Mia Montgomery, Brandon Gale, and Christi Eastham. The interactive map displays today’s temperature information for major cities located within the ERCOT grid. Hover over a city to see the most recent temperature forecast.
Note: A Weather Zone is a geographic region designated by ERCOT in which climatological characteristics are similar for all areas within such region. This map displays the various Weather Zones that exist within the ERCOT footprint, but it does not necessarily include all counties that have participation within the ERCOT market.
General Discussion:
Mostly mild temperatures today through Thursday ahead of a strong, Arctic cold front, which will bring not only the coldest temperatures of the winter thus far, but also an extended period of freezing rain, sleet, and snow over a large portion of the ERCOT Region. The cold front will move through most of the state on Friday but not reaching the Rio Grande Valley until early Saturday. Temperatures will plummet behind the front. Saturday’s temperatures will be steady to falling depending on location. Single-digits and teens across most of West Texas Saturday afternoon, 20s along the I-35 corridor, 30s toward Houston, 40s in South Texas. Even colder lows Sunday and Monday mornings, with Monday likely the coldest for the large cities. Single-digit lows will be common over West Texas, teens to 10 degrees in Dallas-Fort Worth, upper teens to low 20s in Central Texas, 20s in Houston, and 20s and 30s over South Texas. It’s quite possible these temperature forecasts trend colder. Possibly even more significant will be the snow, sleet, and ice storm expected to impact a large part of the state between Friday morning and Sunday evening – with peak impacts on Saturday. West Texas will likely see a range of rain, freezing rain, sleet, and snow (snow north, rain south) to start on Friday – with rain chances for the eastern half of the state. The trend could be toward more snow and sleet over West Texas Friday night into Saturday, with rain changing to freezing rain over North Texas Friday night. Saturday will bring widespread frozen precipitation across at least North and West Texas. Mostly sleet and snow West, with sleet and freezing rain over North Texas to start the day. Central Texas could be on the cusp of rain versus freezing rain to start Saturday morning (higher ice chances north and west regions of Central Texas) but could transition to mostly freezing rain with some sleet as the day progresses on Saturday into Saturday night. Houston is looking at rain Friday and into Saturday but could transition to freezing rain Saturday night into Sunday (bigger question mark for Houston). There will likely be significant ice and snow accumulations this weekend – especially North and West Texas, but ice may be a major concern into parts of Central Texas. Any frozen precipitation that accumulates this weekend will have a hard time melting before Monday, with many locations remaining below freezing all weekend.
Today:
A fairly typical, quiet weather day today. Highs this afternoon will be in the upper 40s to lower 50s over West Texas, mid-50s in North Texas, while the rest of the state will see 60s and 70s this afternoon. Not as cold tonight.
Tomorrow:
Warmer across Texas on Wednesday. 50s in West Texas (some approaching 60), 60s in North Texas, 70s for the South Central, Coast, and South zones. Mild again tomorrow night ahead of one last warm day on Thursday.
