REGIONAL WEATHER SUMMARY
NATIONAL WEATHER SERVICE SAN ANGELO TX
950 AM CDT SUN MAY 24 2015

The sharp inverted C shaped comma cloud associated with a vigorous
upper level shortwave trough is moving east through the area.
Immediately north and east sides of this trough there moderate rain
is occurring. The rain arcs from eastern Fisher and Nolan counties
through southern Jones county and covers parts of Callahan, Coleman
and San Saba counties.  The entire rain area and upper shortwave are
moving east northeast, both are expected to move east of the
forecast area by this evening.  Moderate rain will cause hazardous
driving conditions in rain areas the next 6 to 12 hours.

Winds are 10 mph or less from the southeast south of the southern
edge of a Nolan, Taylor, Callahan counties line and generally 10mph
from the north or east north of this line. Temperatures are in the
low to mid 60s across the area with partly clearing skies moving in
on the west side of the shortwave trough. It is likely surface
heating will help to develop new clouds on the west side of this
shortwave this afternoon.

A small but potent upper level shortwave will move quickly through a
broad upper level trough west of the area and then east across the
forecast area on Monday and Monday evening.  This impulse is
expected to trigger more showers and storms along the dry line which
will then advance through the forecast area.  Some thunderstorms may
become severe, monitor forecasts and possible future warnings
carefully.

A broad upper level trough will persist west of the forecast area
and continue elevated chances for rain in afternoon and evening
hours through most of the week, especially on Thursday and Friday as
a cold front moves south into the forecast area.
