8/23 – Rob’s “Hottest Summer Temps” Monday Morning Forecast
High-pressure slightly stronger than yesterday, is still centered along to just west of the TX/LA border and remains the biggest influence on the local weather. Its close proximity to the area means low rain potential and HOT TEMPERATURES. From a temp perspective, today seems to be a bit warmer with less mixing down lower dew-points. This is will allow heat indices to reach/exceed 108 degrees over portions of the area.
The remainder of the forecast will be a continuation of the trend starting on Monday. The upper high-pressure will slowly drift north, farther away from the local area. This should both lower temps and heat indices somewhat as well allow for higher rainfall coverage as subsidence is reduced. Models maintain high-pressure over the southeastern CONUS late in the weekend and going into the following week. We will watch the tropics closely as climatology and various models suggest the western Caribbean and southern Gulf need to be watched for tropical development during the long-term.
