From Sean Bellafiore:
The Arctic High responsible for the record setting cold seen across Central Texas is slowly moving eastward and will usher in weather changes as it does. While temperatures today will be warmer than yesterday, you'll still need a jacket for a good portion of the day. Morning temperatures in the teens and 20s will climb into the lower 40s east of I-35 with middle 40s down the I-35 corridor. Temperatures west of I-35 will likely be a touch warmer today, climbing into the middle and upper 40s. Expect some clouds in the morning with scattered sunshine in the afternoon.
High pressure continues to trek eastward, helping to bring southerly winds back to Central Texas. Because our airmass is so dry right now, south winds tonight won't bring up humidity values too much too fast. As a result, overnight low temperatures will still drop below freezing into the middle and upper 20s. As moisture continues to slowly move in, highs Friday will range from the upper 40s near I-45 to the middle and upper 50s near Highway 281. The I-35 corridor should expect highs in the low 50s Friday. Clouds will be more abundant east of I-35 with a low chance of an isolated shower while more sunshine should be expected to the west.
Moisture will start to really surge back in Friday night as an area of low pressure begins to form over the Rockies. Temperatures to kick off the day Saturday will only fall into the middle 40s with afternoon highs climbing into the upper 60s to near 70°. Again, another low chance of a shower is in the forecast Saturday with rain chances near 20%.
The best rain chances this weekend arrive Sunday as an area of low pressure moves across the Central Plains while the trailing cold front moves across our area. Scattered showers and thunderstorms should form in the late morning west of I-35, but coverage of rain will slowly ramp up near and east of I-35 in the afternoon. Rain and storms Sunday will be scattered, so some areas may miss out on rainfall. Severe storms are not in the forecast Sunday, but an isolated storm or two may have 40 to 50 MPH wind gusts. Rain chances Sunday are near 50% as highs reach the upper 60s and lower 70s. Cooler air moves in behind Sunday's front, but temperatures early next week should stay in the low and middle 60s.
