LONG TERM. /Mid Week Through Next Weekend/

A few dry and seasonably cool days are expected Tuesday and Wednesday, as we start the day near or just below freezing before recovering into the upper 40s and 50s in large part due to plentiful sunshine and weak westerly low level flow. Continued northwest flow with occasional fast-moving impulses should lead to occasional rounds of mid-high clouds traversing quickly southeast across the area. No precipitation is expected with a coat needed early each day, being shed for possibly a lighter jacket or hoodie each afternoon for those looking to get those last minute holiday gifts.

Our next system will begin organizing over the Great Basin and Central Rockies during the late week period. A shortwave ridge overhead on Thursday will give way to increasing southwest flow aloft and increasing low level warm advection to end the week. Though Thursday will be rain-free, increasing moisture advection, and lift from this next system may allow for low convective chances by Friday and Friday night. By the weekend, this system closes off near or east of our area with our area predominately on the subsident side of the system. Low level dew point temperatures and moisture depth/quality are not expected to be impressive with this system. I only expect isolated-scattered, high-based or elevated showers, though a few rumbles of thunder can't be ruled out from time to time thanks to steepening lapse rates aloft associated with the colder core of this mid level low. Better moisture and storm potential will likely remain relegated well east and southeast of our area across the Gulf Coast and Deep South.

Temperatures will moderate back to mild conditions as we approach the Winter Equinox next Sunday. Thanks to the aforementioned dry low level airmass; low temperatures each morning Friday and next weekend will start off on the chilly side from the mid 30s to mid 40s, while the dry airmass warms into the upper 50s and 60s each afternoon. We may have to watch for elevated grass fire conditions across western Central Texas when south winds will range between 15-20 mph with a few higher gusts to go along with low humidity values. Otherwise, the drier than normal trend on precipitation continues.

SHORT TERM. /Issued 1230 PM CST Sun Dec 15 2019/ /Through Monday/

Synopsis: A cold front will push through North and Central Texas later today, with a stronger push of gusty northerly winds and cooler temperatures expected on Monday. Showers and a few thunderstorms will be possible east of I-35 beginning late tonight, but neither severe weather nor heavy rain is expected.

Morning surface analysis reveals a 1005 mb low near Graham, TX, with a cold front extending to the northwest along a line from the surface low to Floydada, TX to Tucumcari, NM. Temperatures are in the 30s and 40s north of the cold front, with temperatures in the 50s and 60s noted in the warm sector. This cold front will make its way across the Metroplex and the rest of our CWA during the next several hours. In the upper levels, strong zonal flow is noted across the southern tier of the CONUS, with a highly amplified shortwave trough beginning to dig into the Rocky Mountains.

As mentioned above, the cold front will traverse our CWA during the next several hours. The cold front passage will be noted by a wind shift out of the northwest to north, with gradually falling temperatures. Overnight lows will drop into the 30s across much of North Texas, and into the 40s in Central Texas. A light freeze will be possible north of a Breckenridge to Decatur to Gainesville line. East of I-35, there may be enough moisture to allow for some showers to develop. In addition, high-res guidance shows that some instability will be present, so opted to include a low-end thunder mention as well. Severe weather is not expected.

By Monday morning, an Arctic high will build south into the Southern Plains, while a surface low deepens over the Mississippi Valley. In response to the tightening pressure gradient, northerly winds will increase into the sustained 15-20 mph range with gusts to near 30 mph. Right now, it looks like winds will remain below advisory criteria, but the winds will be breezy enough that you will want to secure outdoor items, especially those giant inflatable Christmas decorations. Monday will be quite chilly, as strong cold air advection will keep our highs in the 40s across virtually the entire CWA. The gusty northerly winds will keep wind chills in the 30s across North Texas, and in the 40s in Central Texas. All in all, Monday will be a great day to stay inside with a book and some hot chocolate.

AVIATION. /Issued 1230 PM CST Sun Dec 15 2019/ /18Z TAFs/

After a foggy and dreary start to the day . fog and cigs have lifted across the region. A cold front is located just northwest of the Metroplex at present time . with FROPA expected during the next couple of hours in the Metroplex . and later this evening for KACT. The FROPA will be marked by winds veering out of the N.

Late tonight and into Monday . increasing ascent and a tightening pressure gradient will lead to increasing N winds with gusts to near 30 KT possible during the day Monday. Areas of SHRA with a few TSRA may develop east of a KPRX to KCRS to KGRK line . but impacts are not forecast at any TAF sites. There could be enough coverage to result in some minor impacts to the Cedar Creek arrival gate however . with the most likely time for impacts being 09Z-12Z Monday Finally. lowering cigs are also expected . with MVFR likely at all terminals by daybreak. Some patchy DZ/BR may also develop. Cigs and vsby should improve during the early afternoon hours . but gusty north winds will continue through the end of the TAF period.
