Canadian high pressure settling into Texas over the weekend brought with it some noticeably cooler and drier air. High temperatures Sunday were mostly in the middle 70s. Low temperatures this morning were generally in the mid and upper 40s across the Hill Country and Central Texas regions and in the low 50s across the coastal plains. According to LCRA's Hydromet, the lowest temperature observed this morning was 37 degrees at 4 separate Hill Country locations.
A broad ridge of high pressure in the upper atmosphere over the south central US is currently causing very stable weather conditions across the region. At the surface, the large dome of Canadian high pressure that was over our area Sunday has begun moving off to the east. This has brought a return of southerly winds to all of South and Central Texas. The air remains dry for now and this will allow temperatures to warm very efficiently this afternoon. Today's readings are expected to top off near 80 degrees at most locations. Expect south winds to increase to around 10-15 mph. Low temperatures Tuesday morning will be in the upper 50s across the Hill County, with low 60s at most other locations.
Mostly sunny, dry and warmer weather is forecast Tuesday and Wednesday. A trough of low pressure tracking east out of the southern Rockies Tuesday will cause the West Texas dry line to surge to the east, allowing dry and warm air from Mexico to spread east across the Hill Country and the Interstate 35 corridor. The temperature is forecast to climb to the mid and upper 90s across the Hill Country and to around 90-92 degrees across the Austin and Interstate 35 corridor. Locations further east should see highs in the mid and upper 80s. Expect a southwesterly breeze at 10-15 mph. Low temperatures Wednesday morning are forecast to be in the low 60s across the Hill Country and around 70-72 degrees at most other locations.
There will be a very slight chance for a few rain showers and isolated thunderstorms for areas along and east of Interstate 35 Wednesday morning into Wednesday afternoon when a cold front sweeps southeast out of West Texas. The lack of significant moisture will limit the development of significant totals of rain. For areas that do happen to pick up some rain, totals should average well under a quarter inch. Wednesday's temperatures is forecast to be a bit lower thanks to the passage of the cold front. High temperatures will generally be in the mid and upper 80s. The cold front is forecast to push off the middle Texas coast Wednesday evening, allowing slightly cooler air to filter in from the north. Lows Thursday morning will range from the low and mid-50s across the Hill Country to near 60 degrees near the coast.
Mostly sunny and dry weather is forecast Thursday and Friday in the wake of Wednesday's cold front. High temperatures Thursday will be mostly in the mid-80s. Warmer temperatures are forecast Friday as the dry line again spreads east into Central Texas. High temperatures Friday are forecast to be in the low 90s across the Hill Country and the Austin/Interstate 35 corridor. Elsewhere, high temperatures are forecast to be in the upper 80s.
A Canadian cold front is forecast to push southeast across the region Saturday afternoon into Saturday night, bringing slightly cooler air. Forecast solutions indicate an area of rain showers and scattered thunderstorms will develop along the cold front across the Hill Country Saturday afternoon, with the activity spreading southeast Saturday afternoon and Saturday night. The probability for rain is forecast to be near 20 percent across the Hill Country and near 30-40 percent across Central Texas and the middle Texas coast. The chance for rain should end from west to east late Saturday night into Sunday morning. Rain amounts are forecast to only average around a half inch, or less. High temperatures Saturday will generally be in the mid and upper 80s. Lows Sunday morning will range from the upper 50s west to the low 70s near the coast. High temperatures Sunday will be near 78-80 degrees.
Looking ahead to next week, sunny and dry weather is forecast Monday through Wednesday. High temperatures Monday will be near 80 degrees High temperatures for much of the rest of the week are forecast to be in the mid and upper 80s. Low temperatures throughout the week are forecast to be in the 60s. The long-range solutions indicate a wet and unsettled pattern will develop across the area late next week into next weekend when a trough of low pressure slowly tracks east out of the Desert Southwest.
