Area Forecast Discussion National Weather Service Fort Worth TX 528 AM CDT Wed Jul 1 2020 .SHORT TERM... /NEW/ Update: No significant changes are needed to the forecast as the hot and humid weather continues. The Heat Advisory remains in effect today with afternoon heat indices between 100-110 degrees this afternoon. Expect breezy conditions again today but averaging slightly lower speeds and slightly less frequent gusts than the past 2 days. Stratus early this morning will quickly break up by late morning and midday. Hi-res model guidance continues to show storms developing in parts of West Texas and the Big Country later today. The models merge these storms into a small complex that moves south, avoiding our western counties. Therefore, have maintained a dry forecast with just silent 10 PoPs in our west and southwest counties. JLDunn Previous Discussion: /Wednesday and Wednesday night/ The main headline for today and tonight continues to be the heat, and the Heat Advisory remains in effect for nearly all of the region today, and then continues on Thursday (see Long Term discussion below). Currently, dense cirrus covers most of Central Texas as thunderstorm anvils from storms near San Angelo spread through this area. Just south of the CWA, low level stratus is developing and preparing to spread north. The stratus will spread north overnight, but should start to break up around mid to late morning. The upper level ridge currently centered in the western GOM will quickly strengthen to the north today, over North and Central Texas. This should result in slightly less cloud cover this afternoon versus the past few days and slightly warmer temperatures. High temperatures today will be about a degree or two warmer than yesterday with values largely in the mid to upper 90s. However, the upper level ridge will not reduce the humidity, and heat index values will continue between 100-110 degrees this afternoon. Breezy afternoon winds will provide a little relief from the heat, but am not expecting the winds to be quite as strong and persistent today with the strengthening ridge. However, sustained winds will still average 10-20 mph with gusts up to 25 mph for a good part of the day. Afternoon convection will likely again form on the dryline, but the dryline's location will be farther west today, and the storms aren't expected to reach North Texas. Overnight lows will again be warm in the upper 70s with temperatures around 81 degrees in the Metroplex. The status invasion does not look as prominent for Wednesday night, therefore the sky cover mentions mostly clear for now. JLDunn && .LONG TERM... /Issued 302 AM CDT Wed Jul 1 2020/ /Moving Into The Holiday Weekend - Early Next Week/ Hot and Humid weather continues through Friday with high temperatures between 95 to 100 degrees expected...except for the typical more humid areas of East Texas where lower 90s are forecast. These temperatures aren't considered extremely hot by North and Central TX standards. However, when combined with surface dew point temperatures in the 70s Thursday afternoon you get heat index values rising to between 105-100 degrees. These values will be most prominent north of I-20 and east of I-35/35W where richer tropical moisture is expected to pool. We will be maintaining the current Heat Advisory Thursday as these heat index values can cause one's body to not be able to cool efficiently due to the high humidity. Please keep this in mind if you plan on exercising or working outdoors for any period of time during the daytime hours. Heat exhaustion is a real possibility, so take frequent breaks and drink plenty of water. Otherwise, look for the pressure gradient to relax Thursday afternoon with southerly breezes 10 mph or less. Despite Friday's similar high temperatures, the airmass will likely mix deeper under the strengthening upper ridge with surface dew point and humidity values not being quite as oppressive as on Thursday. At this point, we do not plan on extending the Heat Advisory into Friday, but we'll continue to monitor the trends in moisture and humidity. Wind speeds will even be lighter on Friday as the surface pressure gradient becomes a bit muddled. An outflow boundary from a weakening storm complex moving through Eastern OK and the Ark-La-Tex area late Thursday night is forecast to settle south of the Red River by Friday afternoon. This boundary may act as a focus for isolated to scattered showers and storms across our immediate Red River and East TX counties during peak heating. Thunderstorms will be mostly of the typical garden variety with lightning and very localized, torrential downpours being the primary hazards. PWAT values will be elevated and between 1.5-2 inches in this area with likely slow and erratic storm movement due to weak steering winds aloft. As is typical with Summertime storms, gusty downbursts winds can't be ruled out in and near any stronger storms. Severe weather is not expected. For the holiday weekend and into early next week, high temperatures should slowly fall back closer to normal values. The upper ridge will migrate westward across the Southwest Deserts and far West TX. We should see our highs more in the lower-mid 90s, which for early July is more around normal. Our western counties along and west of Highway 281 will likely be a few degrees hotter being closer to the ridge. In addition, stronger subsidence and mixing will allow for this area to see the lowest afternoon humidity each afternoon. I expect mainly low coverage of showers and storms across our eastern counties each afternoon, despite better forcing remaining well to the east. The main driver for daily storm activity across East Texas will be richer moisture and weaker inhibition aloft thanks to being further away from the retreating upper ridge. Similar to Friday's storm potential, weak winds aloft and weak inhibition will result in mainly slow moving, non-severe thunderstorms with localized heavy downpours across East Texas until just past sunset each evening. For those planning outdoor activities and wanting to watch fireworks after sunset this weekend, most events should carry on as planned, but a few may be slightly delayed. Look for morning lows each day to be typically warm and muggy and in the 70s, except closer to 80 degrees within the immediate urban areas of the DFW Metroplex. Beyond the 7-day forecast, GEFS/EPS ensembles do indicate the upper ridge to our west strengthening and expanding eastward across the Southern Plains and into the Mississippi Valley. Dry and hotter weather appears to be on the horizon in the 7-10 day period (latter half of next week into the following weekend). 05/ && .AVIATION... /NEW/ /12Z TAFs/ Broken stratus is occurring over mainly the eastern half of the region this morning; along and east of I-35. It is difficult to tell how much this stratus will expand into the TAF sites, but with a strong low-level jet still in place, I still anticipate the TAF sites will be impacted by MVFR ceilings for at least a little bit this morning. Ceilings should improve and scatter by midday. Southerly winds of 10-15 kts will prevail today with slightly higher gusts. For this TAF package, I opted to remove the gusts and increase the sustained winds a little as the gusts will likely remain around 20 kts. The winds will subside to less than 10 kts this evening. Stratus is not expected to make a surge across the TAF sites tonight and Thursday morning. Instead, the stratus will remain east and southeast of the airports.
