Increasing pres gradient near the i-35 corridor to translate east
overnight with south winds picking up to around 10 kts durg the
day, with gusts over 20 kts over portions of NE tx. As the deep
low pressure system moves SE into tx panhandle, these winds will
maintain thru the 13 06z fcst cycle, by which time tstms can be
expected to begin developing just west of the cwa. Upper lvl
clouds will continue to thicken durg the day with scattered layers
after 12 12z bemcg lowVFR bkn decks in the aftn. Some of these
decks may lower to high MVFR over NE tx by 13 00z, and across much
of the CWA by 13 06z. 07 .

short term... Tonight through Wednesday
cold high pressure at 1028mb is over n.O. La and has moved on with
s SW winds and sunshine have given us a really nice day. Pretty
average for mid december temp wise. No frost tomorrow with the air
off the gulf much warmer with moisture increasing on all levels.

Cirrus today will become overcast low and mid clouds during
Wednesday with a slight chance for showers developing late in the
day, but then ramping up big time overnight.

The best news is that moisture return has been slow and will not
support more than an inch or inch and half of rain this go around
per wpc day two. So great news for high water issues still
developing from the last go around of 3 to 6 inches. The spc
continues a marginal risk for day 3 and general for late wed. This
is essentially another deep upper low and surface low moving out
of NE tx along i-20 into ms by midday on Friday.

Long term... Thursday through Tuesday by Thursday morning, a
vigorous upper trough will be moving east from the southern texas
panhandle towards north central texas. At the surface, a strong
surface low will be just north of the dfw metroplex with a pacific
cold front trailing south from the low. A line of thunderstorms
should be ongoing from southeast oklahoma to the texas gulf coast.

This line of storms will quickly move east across the area during
the daytime hours. Some timing differences still exist among the
models. However, it appears a dry slot will move into the area as
the upper trough approaches. This should move the most intense
convection east of the forecast area by early Thursday afternoon.

Severe weather cannot be completely ruled out. Damaging winds and
large hail will be the primary threats. The biggest limiting
factor will be the lack of surface instability, but there may be
enough elevated CAPE due to the cold core low to support a few
severe storms.

There will also be quite a bit of post-frontal rain wrapping around
the upper trough as it moves east of the area Friday. The precip
should finally end from southwest to northeast beginning Friday
evening and exiting southwest arkansas completely just after
midnight Saturday morning. Snow was removed from the forecast with
this package as it appears the precip should exit before
temperatures are cold enough. However, an hour or two of very light
snow or flurries cannot be completely ruled out in the ouachitas of
southeast oklahoma and southwest arkansas, but the overall chances
are very low.

Dry weather should return and prevail for the remainder of the
weekend and into the beginning of next week. The pacific airmass
behind Thursday's front will provide very little in the way of
temperature change. The coldest temperatures will be Friday and
Friday night, mainly due to the cloud cover and rain. However,
temperatures will rebound by Sunday returning to near seasonal norms.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
