SHORT TERM. /Issued 1208 PM CST Wed Jan 22 2020/ (This afternoon through Thursday)

Warm moist advection is occurring near and atop of a stubborn shallow cold layer which will continue to lead to the development of low clouds, drizzle, and fog through the afternoon hours. Some bonafide light rain associated with more substantial mid/upper level isentropic lift will continue to impact mainly the southeast half of the area through the afternoon hours. Have lowered today's high temperatures a few degrees, and would expect the northeastern zones to remain in the 30s today with low to mid 40s across the central zones. Some stronger southerly flow over the western zones will erode the shallow cold airmass more thoroughly and a few breaks in the clouds are possible by late afternoon with temps reaching the upper 50s there. Fog should generally continue to develop through the afternoon hours across the central and eastern zones as moisture is continually advected into an already saturated airmass, but would expect visibility with this fog to stay above 1 mile through sunset.

This evening the fog is expected to become more widespread and thicken with visibility dropping to near a half mile or less. It is not entirely certain that dense fog will develop tonight, but it's a good possibility. We will hold off on issuing a dense fog advisory until the trends reveal themselves later this evening. Right now it would appear the central zones are the most favored area for dense fog. Temperatures will hold steady in most areas tonight in the 40s.

A lot of the mid and upper level lift responsible for the current radar echoes will vacate the area to the east this evening and therefore the PoPs will taper down with time. However, as a stronger shortwave impulse drops into the area from the northwest after midnight, strong forcing for ascent combined with some low amounts of elevated instability should result in a few showers and perhaps an isolated thunderstorm - mainly impacting the area north of a line from Bowie to Fort Worth to Athens where overnight PoPs will be highest and isolated thunderstorms have been included in the forecast.

The departure of the shortwave trough in the early morning hours will take the rain chances with it. Winds will switch to the northwest resulting in some clearing from west to east, but likely the models are too aggressive with the scouring out over the eastern zones. Have therefore forecast temps near 60 in the sunnier western zones, but have sided with the cooler and cloudier NAM guidance over the eastern zones which keeps highs only near 50.

TR.92

LONG TERM. /NEW/ /Thursday Night through Wednesday/

The strong upper disturbance responsible for the rain and drizzle today will be departing the area by Thursday evening. Any lingering cloud cover over the eastern counties will continue to push east through the night allowing temperatures to fall into the mid and upper 30s areawide by early Friday morning. Surface high pressure building into North Texas beneath a passing shortwave ridge will result in a rather nice Friday afternoon with highs topping out in the low to mid 60s under sunny skies. The cloud free skies will be short lived though as moisture will begin to spread back across the region on Saturday. A pair of mid level disturbances, one in the Southern Plains and one moving through northern Mexico, will result in an increase in mid and high level cloud cover through the day. Saturday should be a dry day with highs in the mid 60s, but by late evening as stronger forcing for ascent from the Plains shortwave arrives, we should see some scattered showers begin to develop. Right now, it looks like a quick shot at rain chances mainly across the eastern half of the region.

This disturbance moves by quickly and skies should begin to clear out again by late Sunday. Yet another strong upstream shortwave will begin to dig across the western U.S early next week. We'll see additional rain chances overspread the region by Tuesday. Latest model guidance has shifted the axis of heavier precipitation a little farther east, so we'll continue to refine these mid week PoPs over the coming days.

AVIATION. /Issued 1208 PM CST Wed Jan 22 2020/ A shallow cold airmass with strong warm/moist advection just above the surface will ensure IFR/LIFR conditions across most TAF sites through sunset. After sunset, expect the ceilings and visibility to fall to VLIFR. 100-200 ft ceilings and visibility of at least as low as 1/2 mile seem likely. This may drop to 100 ft and 1/4 mile between 3z-12z, but have not indicated that in the forecast yet.

Mostly drizzle or light rain is expected this afternoon and evening. A stronger shortwave will swing through the region after midnight which should ignite some elevated showers and perhaps a storm or two near the Metroplex between 7 and 9z. Have indicated a VCTS for this potential at AFW/DFW/DAL. All of the elevated convection will move out of the region by early morning Thursday with a cold front switching winds to the northwest at 5 to 10 mph and increasing to near 15 mph. This should help bring visibilities up to 1/2-1 miles after sunrise, and to MVFR by late morning, but the low ceilings should be slower to lift and clear with IFR or MVFR persisting into midday or early afternoon.

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.
