concerning taf sites ktul/krvs/kbvo/kmlc/kxna/kfyv/kfsm.
Surface ridge overhead tonight will maintain VFR conditions and
light winds. Data from various models indicates the low levels will
be too dry for fog tonight...and thus have removed mention. The
ridge slides east on Saturday...with south winds returning to
eastern OK by midday. Winds will gust 15-20kts at the NE OK sites.
Overall a quiet forecast for aviation concerns.

Discussion...
nice Spring weather this afternoon with mild conditions...light
winds and mostly sunny skies. Warming trend will continue into
Saturday as southerly winds begin to strengthen. Fire danger
threat will also begin to increase as a dry air-mass remains in
place.

Initial upper wave/jet streak will move into the area during the
day Sunday with scattered showers and thunderstorms possible. A
few storms could become surface based Sunday afternoon...however
expect main thunderstorm chances to hold off until Monday as upper
trough axis/cold front moves into the area. Could still see a few
strong thunderstorms...but deep layer shear will not be overly
impressive and mainly confined to far southeast Oklahoma into
North Texas.

Weak high pressure builds into the area on Tuesday behind
departing system. Southerly winds will quickly return by middle week
with warm/breezy conditions Wednesday into Thursday. A strong
upper level low pressure system will shift into the northern/Central
Plains Thursday into Friday and provide at least a limited
chance for showers/thunderstorms. Currently...stronger upper level
dynamics are forecast to lift north of the area...but overall
progression of system will need to be monitored into next week.
