convection continues across west central texas late this evening,
and will continue into the early morning hours. Using the latest
radar trends to try to forecast timing into the sites, along with
conditions. Cold front will also spread south through the early
morning hours and bring a chance for at least scattered convection
to develop through sunrise. Convection has played havoc with
ceilings, but as the convection eases, MVFR ceilings should
redevelop and persist through the morning hours on Tuesday.

Unsettled air mass across the area by Tuesday afternoon, with low
endVFR ceilings likely allowing a little more sunshine and
instability to develop and perhaps even a little more shower and
thunderstorm activity.

scattered thunderstorms currently over far western texas will
organize into a complex of storms and move east-southeast across
west central texas this evening into the early morning.

Confidence is high enough to add a 2 hour tempo tsra group for the
kabi/ksjt terminals and keeping vcts at the remaining terminals.

Also, expect mainly MVFR ceilings for the next 24 hours, with a
few hours of low endVFR this evening. A cold front will move
south across the area Tuesday morning, with winds becoming north.

short term...

(tonight and Tuesday)
thunderstorms are developing over the higher terrain of eastern new
mexico this afternoon, and are associated with a shortwave trough
moving over the southern rockies. This convection is expected to
move into west texas late this afternoon and early evening, before
overspreading much of our area later this evening and early tonight.

The time frame for the convection across our area is mainly in the 8
pm to 2 am time frame. A few strong to severe storms will be
possible in our area. The main severe weather hazards will be large
hail and damaging winds. If sufficient organization occurs and a
collective cold pool develops with the convection to our west, could
have strong winds on the leading edge. Steepened mid-level lapse
rates and sufficient vertical shear will support a large hail
threat. However, this looks to be a lower end severe weather threat,
and not the magnitude which our area experienced late last week on
Thursday and Friday.

With a broad upper trough over the plains, a cold front will push
south across west central texas on Tuesday morning. Could also have
a weak embedded disturbance entering the southern plains Tuesday
morning. Carrying chance pops for showers and thunderstorms, with
rain chances dropping off from the north during the afternoon. With
considerable cloud cover through much of the day Tuesday, along with
weak cold air advection behind the front, temperatures on Tuesday
will remain on the cool side with afternoon highs expected to be in
the lower to mid 70s.

long term...

(Tuesday night though Monday)
more stable and drier air will move in behind the cold front
Tuesday night. With surface high pressure and light winds by
morning, good radiational cooling conditions will be in place...

with lows in the upper 40s to around 50 expected.

The cool air will not last long however, with sunny skies and
southwest winds of 5 to 10 mph Wednesday. Highs Wednesday are
expected in the mid 80s.

A continued warmup with highs in the mid/upper 90s are expected
Thursday and Friday, as a surface low moves east through oklahoma,
bringing gusty southwest to west downslope winds. An upper
disturbance may bring an isolated shower or thunderstorm Saturday,
but the better chance of storms is Saturday night and Sunday, as
a cold front GOES through. Both the ec and GFS models have some
weak upper disturbances moving through early next week, with
continued potential for isolated showers or thunderstorms.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
