AVIATION. /12Z TAFS/

A cold front continues to move through the region this morning and all TAF sites now have a northwest wind. VFR prevails across the area with the exception of a small patch of MVFR cigs which have spread across DAL over the last hour. These should primarily stay to the east of the major airports through the morning, but we'll continue to monitor this. The western edge of these lower clouds could perhaps spread over DFW through 14Z. Otherwise, northwest winds will become more northerly through this afternoon and we should see an increase in high cloud cover into the evening hours.

Moisture will remain in place just above the shallow cooler air mainly east of I-35. Some of this may spread westward back toward I-35 during the overnight hours and should primarily be a concern at Waco by early Saturday morning. We'll keep things VFR for now, but may need to add some lower cigs if trends continue.

SHORT TERM. /Issued 304 AM CST Fri Dec 6 2019/ /Today and Tonight/

As of early this morning, a cold front continues to move through the area and is positioned from near Sherman to Alliance to Comanche. Temperatures are still in the mid 50s, but northwest winds are invading the area and are gusting to near 30 kt across our northwest counties. The center of the surface low is located across far southeast Oklahoma and this will continue to move off to the east through the morning allowing colder air to filter into the region. Despite strong forcing for ascent associated with a passing shortwave, limited moisture has resulted in only widely scattered light rain showers mainly well off to the north and east. We'll keep PoPs out of the forecast through the morning hours. Some lower cloud cover could persist mainly east of I-35 into the afternoon hours.

Northwest winds will gradually become more northerly today, but will stay up into the 15 to 20 mph range. Temperatures will likely remain in the low/mid 50s along the Red River with lower 60s to the south behind the front. Another digging trough approaching the West Coast of the U.S. will mean that the southern branch of the jet stream will be positioned over the Southwest U.S. This should result in an increase in high cloud cover, especially later in the day.

By tonight, we'll remain within the shallow cool airmass with a weakening northerly flow. There will be some moisture just above the shallow frontal inversion and as winds above the surface become more easterly overnight, some lower cloud cover could spread back westward toward the I-35 corridor. While no precipitation is expected, the increased cloud cover will impact overnight lows. Lows will drop to near freezing across our northwest counties, while areas from I-35 eastward are likely to remain in the 40s.

LONG TERM. /Issued 304 AM CST Fri Dec 6 2019/ /Saturday onward/

Synopsis: After a relatively benign week, a return to a more active pattern is in store for next week. Temperatures will be near to a little below normal, along with increased rain chances. Still, widespread hazardous weather appears unlikely at this time.

We will start off the forthcoming weekend with upper-level ridging. This will mean milder temperatures by Sunday (Saturday will still be cool owing to Friday morning's frontal passage), and rain-free conditions. A subtle shortwave trough will pass across Oklahoma on Sunday, but the only impact on our sensible weather will be slightly increased cloud cover (and even then, only high clouds).

Heading into the work week, global models are in good agreement that a deep mid-tropospheric trough will dig into the interior CONUS. This should help to drive a cold front across North and Central Texas during the day Monday. Rain showers should develop along and ahead of the front, with a few thunderstorms possible across parts of Central Texas where low-level moisture will be more abundant. Rain will persist into Monday Night as positive differential vorticity advection over the region continues to promote vertical ascent. While temperatures will fall behind the front, the freezing line should still be well to our north up in northern Oklahoma or even southern Kansas, thus winter weather will not be a concern. Rain should taper off during the day Tuesday as the upper-level trough axis shifts to the east, and upper-level heights rise. Cool temperatures can be expected on Tuesday, with highs struggling to get out of the 50s. Breezy north winds will keep wind chills in the 40s all day. Tuesday Night will be the coldest night of the week, with lows likely to be in the 30s across the entire county warning area. A light freeze appears likely for areas north and west of Dallas/Fort Worth (with the urban core of the Metroplex itself likely remaining just above freezing).

We should get a brief break in the rain on Wednesday, before another deep upper-level trough swings into the western and central CONUS on Thursday. At least low rain chances will exist on Thursday and into Friday along yet another surface cold front, but with moisture content being a bit lower, and some run-to-run model disagreements, we have opted to keep PoPs in the slight chance to chance categories at this time.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
