715 PM CDT Tue Jun 14 2022 ...New Short Term, Aviation... .SHORT TERM... /NEW/ /Through Wednesday Night/ A warm and breezy evening is taking shape across the region. A plume of Saharan Dust continues to move through, making the skies a little hazy with a faint orange tint. This is ahead of the strawberry supermoon tonight...so those (select few) unaffected by passing cloud cover may be in for a nice treat tonight. The winds have been exceptionally gusty out of the south this afternoon with some locations within D/FW gusting up to about 40-45 mph a few hours ago. This is a result of the area being sandwiched between weather systems with multiple low pressure systems to our west and a strong high pressure center to our east. The winds tonight will weaken some, but remain gusty as warm and moist advection prevents the boundary layer from fully decoupling. A surge of gulf moisture will also move north, making tomorrow morning feel like a typical Summer morning...warm and humid. Most will wake up to a blanket of early morning stratus that should eventually lift and scatter by mid to late tomorrow morning. An upper low is currently moving north along the upper Rio Grande Valley and will settle into the Hill Country and Concho Valley tomorrow. Typically, this kind of system would bring showers and thunderstorms but not this time. The system is battling abundant dry air in the mid-levels, so the lift and moisture flux is simply not enough to overcome this. It`s main effect on our weather will be passing upper clouds for the next couple days before it fills and gets absorbed into the mean flow late this week. The cloud cover will weaken insolation and allow afternoon temps to mostly remain below 100 degrees for the first time in several days. Unfortunately, the lower temperatures will be counteracted by increased moisture, so heat index values should still be in the low 100s.

While it will primarily be centered across the lower Mississippi Valley, the strength of the ridge will ebb and flow as it interacts with other synoptic features. The ridge will be in its weakest state over our region Friday and Saturday when a slug of moisture and a weak upper level disturbance will move in from the east. (This system is currently responsible for the convection across Georgia and South Carolina today.) The increase in precipitable water will result in some surface instability Friday afternoon and Saturday afternoon across the southeastern zones. However, subsidence will remain strong, and forcing for organized lift will be weak or non- existent. Will show just a 10% chance of showers/storms in the southeastern half of the CWA where moisture will be best for stray late afternoon and early evening showers/storms. Otherwise the ridge will ever so slightly build over the region again by Sunday and Monday with no chance of rain next week. High temperatures will be in the upper 90s to near 100 degrees Thursday through Sunday, but warm a couple degrees next week. Lows will range from the mid to upper 70s through the weekend, but also increase a few degrees next week. Due to the increased moisture Friday and Saturday, heat index values will likely meet or exceed 105 degrees across the eastern zones and will remain near this level into next week. This likely means heat advisories will return for areas along and east of the I-35 corridor. TR.92 && .AVIATION... /NEW/ /00Z TAFs/ Saharan dust is lowering the slant range visibility for ARR/DEP aircraft as a plume of dust moves across the region this evening. Lower dust concentration tomorrow morning should limit it`s impact during sunrise. Gusty south winds and VFR will prevail tonight before a surge of MVFR stratus moves over the area in the early morning. Ceiling heights should flutter between 1800-2200ft, but for the most part cloud bases should remain AOA 2kft. Expect the MVFR ceilings to first move over the ACT terminal around 06-08Z, then the D10 terminals an hour or two later. The ceilings will then lift and scatter to VFR by mid-morning, but passing upper clouds will allow for intermittent VFR ceilings through the remainder of the TAF period.
