SHORT TERM. /Issued 1255 AM CDT Sat Aug 15 2020/ /Through Saturday Night/

Another day of oppressive heat is in store with roughly the western half of the forecast area expected to reach Excessive Heat Warning criteria. Temperature readings will meet or exceed 105 for most locations within the warning, while heat index values climb to around 110. The remainder of the forecast area should see heat index values climb into the 105-108 degree range, and a Heat Advisory will be in effect through this evening. Otherwise, fire weather conditions will remain elevated west of I-35 due to low humidity, very hot temperatures, and an ample supply of cured fuels.

Meanwhile, a surface trough axis will become draped west to east through North Texas today, associated with a thermally-driven surface low located to our west. There is a small chance that weak convergence near this feature could ignite a thunderstorm or two during peak heating, which would be most likely near the I-20 corridor west of I-35. This potential is rather low, mainly due to the fact that most moisture should have thoroughly mixed out by the afternoon and the column overall will be quite dry. Will keep an eye on new guidance this morning for possible inclusion of some small PoPs, but silent 10% chances will suffice for now.

Additional upstream convection is possible late this evening and tonight which may spread towards our northwestern zones similar to yesterday. At this time, none of this activity is expected to affect our CWA, although it may send some high clouds or an outflow into the area again.

LONG TERM. /NEW/ /Sunday through Next Weekend/

North flow aloft around the east side of an amplifying ridge centered off to our west will send a cold front south to near the Red River by Sunday. The front will make slow and steady progress southward through North Texas Sunday evening and Central Texas Sunday night, bringing a chance of showers and thunderstorms along with a welcomed end to the current heat wave.

A stationary front will already be situated somewhere near the I-20 corridor on Sunday ahead of the main cold front. Isolated thunderstorm development is possible in the vicinity of this boundary during peak heating hours Sunday afternoon. For this reason, we will hold off adding one more Heat Advisory for Sunday, as there remains too much uncertainty with regard to convective coverage and its effects on temperatures. If storms struggle to develop, then areas along and south of I-20 will no doubt reach Heat Advisory criteria. The opposite will be true of thunderstorms do develop and limit afternoon insolation, so will wait until later today or tonight before making a decision regarding the advisory. Either way, one last day of above-normal temperatures can be expected as we close out the weekend.

Additional chances of showers and storms will occur Sunday evening and overnight as a subtle shortwave and the cold front both progress southward through the region. Though good levels of moisture and instability will be present, weak shear will likely keep storms disorganized and sub-severe. Slow storm motion may provide an opportunity for locally heavy rain, but soils have become somewhat moisture-deprived and should be able to tolerate any good rainfall totals which may occur.

Storms may occasionally form in clusters as activity works its way south overnight Sunday night and Monday, with activity likely remaining sub-severe. Chance POPs will continue mainly south of I-20 during the day Monday, and across the southern-most counties Monday night as the front slows and begins to stall. Monday temperatures will be much closer to normal with highs ranging from the lower 90s along the Red River to the mid and upper 90s across Central Texas. The rest of next week will be characterized by near-normal temperatures as little change in the upper level pattern is expected. Low rain chances will return by the end of next week as a weak inverted trough sneaks in from the east, with temps remaining near-normal as we enter next weekend.

AVIATION. /Issued 1255 AM CDT Sat Aug 15 2020/ /06z TAFs/

VFR will prevail through the period. For the Metroplex airports, winds will gradually turn to the east by midday as a surface pressure trough becomes draped near the I-20 corridor, although speeds will remain around 10 kts or less. Waco, however, should remain on the southern side of this feature, keeping winds mostly out of the southeast. Sky cover will consist of some passing high clouds and a few diurnal cumulus around 6-8 kft.

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