Area Forecast Discussion
National Weather Service San Angelo TX
348 PM CDT Tue Sep 26 2017

.SHORT TERM...
(Tonight and Wednesday)

Water vapor imagery this afternoon depicts a deep upper low spinning
over the Desert Southwest with disturbances rotating around the
eastern periphery of the low. Meanwhile, a cold front is draped
across the Big Country with temperatures in the 50s and 60s behind
the front. Widely scattered showers and thunderstorms continue
streaming north across the area mainly across the Big Country closer
to the aforementioned front. The front will continue moving slowly
southward overnight with additional showers and thunderstorms
developing along and behind the front. A stronger disturbance
embedded in the southwesterly flow aloft will swing across the
southern half of the area overnight and into tomorrow providing
additional lift. Thus, will continue with likely POPS for the entire
area through Wednesday. The main hazard will continue to be the
possibility of heavy rainfall as precipitable water values remain
elevated. The flash flood watch will remain in effect through
Thursday.

.LONG TERM...
(Wednesday Night through Tuesday)

Will keep the Flash Flood Watch going through Thursday, as another
round of heavy rain will be likely Wednesday night and early
Thursday morning as the low level jet kicks in overnight. Expect
area of heaviest rain mainly along I-10 corridor in the vicinity of
the old frontal boundary. Heavier rain will taper off Thursday
evening and Friday as a surface ridge builds in and moisture
decreases, but will still carry a chance of lighter rain through the
early part of the weekend. Expect cool and cloudy conditions to
continue on Saturday with highs in the 70s. Dry by Sunday into the
early part of next week with more zonal flow aloft. Expect a slow
warming trend as highs climb back into the mid to upper 80s by
Tuesday.
