DISCUSSION...

With wind gusts increasing across much of South Texas this morning
have gone ahead and issued an RFD statement for elevated fire
weather conditions possible. Northerly wind gusts of 18 to 25 kts
will be likely for the next several hours with rh values dropping
into the teens and 20s this afternoon. Wind gusts currently are on
track with momentum transfer expectations via rap soundings which
indicate we`ll see the peak of the winds between now and about 3pm
with an improvement thereafter.

AVIATION...

Aviation conditions are improving across South Texas as cold

will predominate throughout the remainder of the period.

late morning, diminishing during the mid to late afternoon.

PREVIOUS DISCUSSION... /Issued 443 AM CST Mon Jan 22 2018/

SHORT TERM (Today through Tuesday)...

A cold front is currently tracking across South Texas towards the
coast early this morning. Ahead of this boundary patchy fog to
areas of fog will persist. As the front moves through though drier
air will enter the region, and the fog is expected to clear near
daybreak. Today will be cooler, with highs topping out in the
upper 60s to lower 70s. Weak to moderate northerly winds can be
expected today, with some brief gusty conditions during the late
morning/early afternoon. Cooler and drier conditions develop
tonight under mostly clear skies and weak winds. Lows will once
again dip into the upper 30s across the northern Brush Country
and Victoria Crossroads, and into the mid/upper 40s along the
immediate coast. Tranquil and dry conditions will persist on
Tuesday with a surface high sinking further south into the region.

LONG TERM (Tuesday night through Sunday)...

Surface high pressure will build into the area Tuesday night into
Wednesday as high centered over the central high plains slides
southward into Texas. This will keep the weak coastal trough near or
south of the lower Texas coast. Northeast winds will maintain cool
and dry air mass over the region Wednesday. High pressure moves to
the east and onshore flow develops on Thursday. A weak short wave
trough over northern Mexico will lift northeast into west Texas
Thursday. Southeasterly low level flow will increase Thursday night
into Friday as surface trough deepens over the high plains in
advance of the upper trough moving through the Rockies. Enough
moisture returns Thursday night for a slight chance of showers with
a slightly better chance over the coastal plains and coastal waters
on Friday. The upper trough swings into the central and southern
plains Friday night into Saturday morning. Scattered showers and
isolated thunderstorms will be possible Friday night into Saturday
with the better chances on Saturday as the front pushes into the
region. Strong offshore flow is expected behind the front Saturday
night into Sunday morning. Cooler and drier air will be in place
behind the front Sunday.
