Area Forecast Discussion
National Weather Service Lubbock TX
1247 AM CDT Sun Sep 24 2017

A north-to-south band of rain with a few embedded thunderstorms
will continue to advance slowly eastward overnight bringing rain
to KLBB and KPVW soon. Additionally, MVFR cigs are expected to
develop and overspread KLBB and KPVW in the 08-10Z time-frame and
persist through the remainder of the morning, though a return to
VFR is possible this afternoon. It is less clear if KCDS will dip
below VFR later this morning, but it should see some residual
showers around or after 12Z. Additional showers and thunderstorms
will be possible at any/all of the terminals Sunday afternoon and
evening, though timing of any thunder impacts is too uncertain to
include in the TAF ATTM. There is also a good chance that ceilings
drop back below VFR late Sunday, though this may not occur until
around or after the end of the TAF window.


.PREV DISCUSSION... /issued 319 PM CDT Sat Sep 23 2017/

Very little change in forecast as run to run NWP has remained
consistent with overall coverage of significant rainfall beginning
overnight tonight as showers and thunderstorms move out of eastern
New Mexico into the Texas Panhandle and South Plains. Extended
periods of showers and storms with occasional breaks in activity
will extend through Tuesday. Showers ill be heavy at times, with a
Flash Flood Watch out for our western counties near Texas/New
Mexico beginning this evening through tomorrow morning.

Slight differences in timing of cold front remain on Monday with
NAM and ECMWF continuing to be slightly ahead of the GFS, but
otherwise we expect one to three inches of wide spread rainfall
across the region with some areas locally receiving five inches or
more between late tonight and Tuesday. Furthermore, as we begin
looking toward the middle and end of next week, GFS and ECMWF both
indicate the cold front stalling somewhere in the vicinity of the
southern South Plains to the I10 corridor. With ample moisture
remaining in place across the region and a secondary trough on the
heels of the current upper level low remaining to our west for the
end of next week into next weekend. WPC seven day QPF continues to
color up to 4-6 inches across our northwest counties and up to 9
inches as you move southeast into the southern Rolling Plains. Obviously
with all the rainfall in the forecast temperatures will be
dropping from now through the end of the week. Still looking at
highs in the 70s to near 80 for most locations tomorrow but we
will quickly see highs drop to the upper 60s and low 70s by
midweek and extend into the weekend as well.


Flash Flood Watch until 7 AM CDT this morning for TXZ021-022-027-
