The Weather Authority | Rain at times through Saturday morning

The Weather Authority: 7-Day Planner December 13, 2018 (

From the ABC 33/40 Weather Blog:

GOING BOWLING: We decided on the WeatherBrains podcast last night that “Bowling Ball” is our new favorite weather word. We typically use it to describe large upper-level lows that tend to barrel across the landscape, creating woes for weather humans. One such low is heading our way on this Thursday afternoon. It is forming over North Texas and southern Oklahoma even as we speak. The deep trough that spun it up is swinging across the Plains right now and it will bring a round of wet weather to the Southeast over the next 24 hours.

ON THE WEATHER MAPS: The surface low that is being generated by this system is intensifying over northeastern Texas this afternoon. It is running up the back of very strong high pressure centered over Maine. The pressure gradient between the deepening low and the strong high is causing surface winds to kick up just to our west and we will see those gusty winds pick up out of the east this evening, averaging 8-16 mph and gusting as high as 25 mph at times. Ridge may even see higher gusts.

NO REPEAT OF SATURDAY NIGHT: While we don’t expect widespread tree damage like occurred with the wake/ low/gravity wave event Saturday night, there could be a few reports of downed trees tonight, especially given our current wet soil conditions.

NAILING DOWN A RAINY FORECAST: A few light showers moved across the area late this morning, and more will continue to form this late this afternoon, but the main rain and storms are moving through southern Mississippi and eastern Louisiana. Rain and some thunder will increase from the southwest after dark tonight, with rain reaching the Birmingham area between 7-9 p.m. Rain will increase in the I-20 Corridor through midnight and into the early morning hours. Showers will be likely into the morning hours on Friday. Rainfall amounts should average one-quarter of an inch by morning. After highs in the 50s this afternoon, lows tonight won’t fall much, dropping into the 47F-54F range.

THE FACTS ON FRIDAY: Tomorrow will be a mostly cloudy, relatively mild day with highs in the upper 50s and lower 60s. Rain chances will remain high throughout the day. At least one band of heavy showers will move through as the low approached Friday afternoon. Rainfall amounts will average less than one-half inch during the day. There could be a little thunder mixed in with that band of showers tomorrow afternoon. Any chances for severe weather should be limited to the Gulf Coast, although we will be keeping an eye on the possibility further to the north. Showers will stay with us through Friday night as the bowling ball lumbers across.

SATURDAY LINGERERS: A little bit of light rain and drizzle will linger into Saturday as the upper low moves into the Mid-Atlantic. Clouds should begin decreasing Saturday night, and after highs in the lower 50s Saturday afternoon, overnight lows will drop into the lower 40s Sunday morning. A few normally colder spots will be well down into the 30s.

SUNDAY: Sunday won’t be a bad day, with increasing sunshine, and highs in the middle 50s.
