Rain chances to begin increasing Friday across Red River Valley region bordering OK/TX although rainfall amounts will remain lgt thru this period of the fcst. /07/ LONG TERM.../Saturday through Thursday Morning/ At the beginning of the forecast period, the remnants of Tropical Storm Sergio will begin to meet up with return flow off of the Gulf of Mexico somewhere over West and Central Texas. As the surface low approaches the ArkLaTex, rain chances will begin to increase by the afternoon timeframe, especially for East Texas, Southeast Oklahoma, and Southwest Arkansas. From Saturday into Sunday, the surface low will track across the I-30 corridor and allow for some heavy showers and isolated thunderstorms. Instability during the entire forecast period will be limited, thus only mentioning thunder for the weekend, and that may be generous. Another round of precipitation will develop on the surface front as it pushes through the four-state region on Sunday. Afterwards by Monday morning, still more showers will develop along and north of I- 30 as southwesterly flow aloft will allow for overrunning of the 850- 700 mb frontal boundary. This setup will remain in place through much of Wednesday until surface high pressure builds in from the north. Overall rain totals will average from 1 to 3 inches from south to north, with the higher amounts along and north of I-30. Some localized higher amounts and some isolated flash flooding could be possible, especially along and north of I-30. With the cold frontal passage late Sunday into Monday, some much cooler air will be in store for our region. High temperatures area- wide will be some 20 to 25 degrees below normal while low temperatures will be 5 to 10 degrees below normal for the remainder of the period. /35/ && .PRELIMINARY POINT TEMPS/POPS...
