An active period of weather is forecast this afternoon and evening, but quiet weather conditions are expected for the remainder of the week. We will see more sunny weather this week as the storm track changes, taking the Pacific storm systems northeast towards Canada instead of across the southern Plains states.
Early this afternoon, a Pacific cold front was slowly pushing southeast out of Northwest Texas. At 2 pm, the front stretched from Crockett, to Austin, to Rocksprings, Sonora and Sanderson. Ahead of the cold front, weather conditions were mostly cloudy, warm and humid with temperatures close to 80. Meanwhile behind the cold front, weather conditions were drier and slightly cooler. The front is forecast to move across Central Texas this afternoon, reaching the Interstate 10 corridor in the early evening. The front is forecast to push off the middle Texas coast around midnight.
At 2 pm, radar indicated scattered rain showers and thunderstorms developing along the cold front from southeast of Austin to north of College Station. Additional thunderstorms are forecast to develop southwest along the cold front as it moves into Central Texas over the next few hours. The line of rain showers and thunderstorms is forecast to slowly spread southeast towards the coast this afternoon and evening.
The Storm Prediction indicates the threat for severe storms will be east of Austin and the Colorado River basin.Severe Weather Outlook for Monday afternoon and evening:
In addition to the line of thunderstorms, a couple of isolated rain showers and thunderstorms will be possible for areas southeast of the front throughout the afternoon. The probability for rain and thunderstorms at any given location from the Austin, southeast to the coast will be near 40-50 percent. The threat for rain and storms should taper off shortly behind the cold front this afternoon into this evening.
Rain amounts from this afternoon's potential storms are forecast to average less than a quarter inch across the eastern Hill Country and Central Texas regions. Towards the coast, totals are forecast to average between 0.25 and 0.5 inches.
This afternoon, temperatures ahead of the cold front are forecast to warm into the low 80s. Behind the front, readings are forecast to fall to the low and mid-70s along with a north wind at 10-15 mph. The sky should clear across the Hill Country and Central Texas regions this evening and towards midnight as cooler air spills in behind the cold front. Lows Tuesday morning will be near 38-40 degrees across the Hill Country, in the low and middle 40s across Central Texas, with low and mid-50s towards the coast.
A large, stable ridge of high pressure in the upper atmosphere developing over the western and southwestern US is forecast to produce a sunny, dry and stable weather pattern across Texas Tuesday through Thursday. We'll see mild days and cool nights. High temperatures Tuesday will generally be in the low 70s, but readings should trend slightly cooler Wednesday and Thursday as cooler air spreads in from the north. High temperatures Wednesday will be in the low 60s, warming to the upper 60s Thursday. Low temperatures Wednesday and Thursday mornings will include the low and mid-30s across the Hill Country, the upper 30s to low 40s across Central Texas and low to mid-40s across the coastal plains. Low temperatures Friday morning will generally be around 50 degrees.
The cool, Canadian air mass is expected to shift east late Thursday into Friday as southerly winds return to Central Texas. These southerly winds will likely cause the sky to become mostly cloudy Friday through Saturday. A few sprinkles of light rain will be possible both days, but significant rain is not expected. Temperatures are forecast to reach the mid-70s Friday and the low 80s Saturday.
A cold front is predicted to move across the area late Saturday, bringing drier and slightly cooler air for Sunday and early next week. Expect mostly sunny conditions next Sunday through Tuesday with high temperatures around 68-70 degrees. Low temperatures will be around 48-50 degrees.
Longer-range solutions call for a slight chance for rain next Tuesday and Wednesday when a weak trough of low pressure moves southeast out of the Plains states. Rain amounts, if any, should total less than a quarter inch. Otherwise, expect a mostly cloudy sky, followed by mostly sunny conditions next Thursday and Friday. High temperatures should trend back into the 70s for the second half of the week while low temperatures remain around 48-52 degrees.Time Change Weekend Coming Up
Daylight Saving Time officially begins this Sunday, March 11, 2018, at 2 am. Remember to "spring forward" and set manual clocks forward one hour before bed Saturday night. The change means sunrise and sunset will be about one hour later on March 11 than they day before, meaning we'll enjoy more light in the evening hours.Sunset Planets
When the sun goes down tonight, step outside and look low in the western sky. If you have a clear view of the horizon, you can see the planets Venus and Mercury beaming together through the rosy glow of sunset. The two bright planets are little more than 1 degree apart. The two planets will remain visible each evening this week.
