.SHORT TERM...
(Today through Tuesday)
Issued at 300 AM CDT Mon Sep 26 2022

A cold front has entered the northern part of our CWA and is
stretched from near Georgetown to Rocksprings to western Val Verde
County. The front is generating showers and thunderstorms that are
moving into our Hill Country and Southern Edwards Plateau counties.
The front will continue to move southward through our CWA and reach
our southern border by around sunrise. Behind the front isolated
convection will continue over the Rio Grande Plains today. It will
move from north to south through the morning and afternoon. The rest
of the CWA should remain dry. The front will usher in northerly to
northeasterly winds that will increase to 10 to 15 mph during the
afternoon over the eastern half of the area. These northerly winds
will bring much drier air. Dewpoints that are in the 60s to lower
70s this morning will drop into the 40s and 50s by this evening.

Today`s high temperatures will be cooler across the north where the
front will pass early in the day and remain well above normal across
the south. The dry air will allow lows Tuesday to cool to about 10
degrees lower than today ending up in the 50s and 60s. Highs Tuesday
will be down to near normal.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 300 AM CDT Mon Sep 26 2022

An upper level ridge over our area mid to late week weakens leaving
a weak zonal flow aloft next weekend. An upper level trough over the
eastern states lifts soon to be Hurricane Ian north over Florida
into the southeastern states. Surface high pressure ridging and a
dry airmass with well below seasonal normal PWs of 1/3 to 3/4 inch
remain through next weekend. The dry airmass combined with subsidence
ensures no rain. High temperatures remain slightly above average due
to ample sunshine. Low temperatures trend to well below average as
low dewpoints, clear skies, and light winds allow for efficient
radiational cooling at night. A few of the normally cooler low lying
spots in the Hill Country to along the Escarpment may briefly fall
into the upper 40s around sunrise.

so. Other than this activity, all airports will be VFR through the
