AVIATION.

For the ArkLaTex terminals increasing low and mid clouds during this cycle with a fropa early on Sunday. Light W/SW winds overnight will veer to NW during the daylight hours and speeds of 10-20KT will spread into the area all afternoon with CIGS gone. Skies will clear out with a good looking start to the week, but VFR goes south for midweek with a stalled front and rainy pattern. /24/

PREV DISCUSSION. /issued 940 PM CST Sat Jan 16 2021/

UPDATE .

Lowered quite a few low south of I-20 and adjusted sky.

SHORT TERM .

Air temps are falling fast where skies remain clear. Our spreads are substantial except where clear and calm now and thus much closer to saturation. So we have padded down clear areas for several more degrees and kept the I-30 lows going. The cloud coverage's leading edge is on an arc from Nacogdoches to Shreveport and El Dorado, all sites that where already down to forecasted lows. So here and points south have been lowered a couple or few degrees with some category changes on the zones. Nothing significant to report aside from some possible patchy frost from Nacogdoches to El Dorado and points SE, which will likely not last under the blanket of clouds by daybreak. /24/

PREV DISCUSSION . /issued 239 PM CST Sat Jan 16 2021/

SHORT TERM . /Tonight through Sunday Night/

Dry northwest flow aloft continues across the region today. Mostly sunny skies and much lighter winds have allowed temps to climb into the 50s areawide. However, clouds will be on the increase this evening ahead of a shortwave trough diving southeastward along the flow. With mostly cloudy skies expected tonight, decided to keep overnight lows a few degrees above guidance. But, still expecting temps in the mid to upper 30s across the region.

The shortwave will move through during the morning hours on Sunday, pushing another cold front through the region. Although there will be abundant upper level moisture for cloud cover, precip is not expected with this system, as low-level moisture is very limited. Gusty northwest winds in wake of the front will bring a reinforcing shot of cooler and drier air to the region, with temperatures falling to near freezing area-wide by Monday morning. /20/

LONG TERM . /Monday through Saturday Night/

We begin the work week with a departing longwave trough moving off the Eastern Seaboard, leaving northwesterly flow aloft in its wake across the Southern and Central Plains. At the surface, ridging will shift east of the CWA with a warming southerly flow prevailing across our entire region Monday through Tuesday. A weak cold front steered by the WNW flow aloft is still fcst to move south and east into our region during the day Tuesday and should be near or just north of the I-20 Corridor of NE TX and N LA by 00z Wed. This front will help to generate scattered showers across mainly our northwest two thirds Tue/Tue Night before the boundary begins to lift back northward as a warm front on Wed.

Meanwhile, a vigorous upper level low, cut off from the westerlies will continue to spin across Baja California during this time frame and will not begin to fill and lift out into the Plains until sometime Thu into Thu Night. It is for this reason that precipitation will likely not become likely across our region until this timeframe as these progs continue to delay the progression of the more substantial precipitation across our region until later in the week. There is pretty good agreement now that the precipitation should end from west to east across our region with the passage of the filling trough and a cold front poised to move from west to east across our region on Friday.

The drier weather may be shortlived however as the trough across the Southern Great Basin reloads for next weekend, suggesting that we could again see scattered showers across our region by late next weekend. /13/

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.
