Rain to continue...

FORECAST DISCUSSION

Rain, heavy at times, will remain in the forecast for the remainder of the weekend and into the first half of the day on Monday as the upper level storm system currently located south of Arizona takes its time approaching the state of Texas. This overrunning pattern, warm, moist air being forced to rise up and over the cool air mass at the surface will continue for the remainder of the weekend locking in the wet and chilly conditions. Overnight lows tonight will remain steady in the upper 40s and lower 50s area wide with highs on Sunday struggling to get out of the lower 50s area wide.

Rainfall accumulation, so far, has been heaviest to the south of the Austin Metro Area. 

Within the past 24 hours this is how much rain has fallen:

•          Camp Mabry has received 1.17 inches of rain.
•          Austin Bergstrom International Airport has received 1.48 inches of rain.
•          Georgetown Municipal Airport has received 1.50 inches of rain.
•          San Antonio International Airport has received 3.88 inches of rain.

***An additional 1-3 inches of rain will certainly be possible by the time rains come to an end sometime Monday***

While severe weather is not anticipated over the next couple of days, minor flooding may become an issue in areas that typically see flooding concerns. Flooding concerns look to be highest south and east of the Austin Metro. Lightning cannot be ruled out within the heaviest of the rainfall activity as well as the possibility for some sub-severe (small) hail.

***FLASH FLOOD WATCH for areas south & east of Austin***

With that being noted, the National Weather Service Austin/San Antonio Forecast Office has decided to issue a FLASH FLOOD WATCH for areas south and east of Austin. This watch includes BANDERA, BASTROP, LEE, MEDINA, BEXAR, COMAL, GUADALUPE, CALDWELL, FAYETTE, WILSON, GONZALES, AND LAVACA COUNTIES from 10pm CST tonight through late Sunday evening. An additional 1-2 inches of rain with isolated amounts of up to 4 inches of rain are possible in those locations.

ARCTIC COLD FRONT TO ARRIVE WEDNESDAY

Latest forecast model guidance continues to indicate that some very cold Arctic Air will be heading south into the lower 48 this coming week. As of right now, the Arctic front looks to arrive in central Texas sometime during the day on Wednesday. If models continue to verify, it looks like all of central Texas will see freezing temperatures behind this front, even right in Austin. Luckily, freezing precipitation does NOT look to be an issue with this particular cold front.
