Rua && .PREV DISCUSSION... /issued 657 AM CDT Thu Oct 11 2018/ DISCUSSION... For 12z TAF issuance. AVIATION... Basically just a wind forecast this go round as sfc obs/satellite imagery indicate clear skies ongoing and forecast soundings show little to no low-level moisture to work with through the period. Elevated nrly flow can be expected again today as the area continues behind the departing cold front and high pressure over the Plains. 25 CLIMATE... As expected, our run of days with temps in the 70s or warmer came to an end on Wednesday...but barely as temps dropped into the 60s between 11pm and midnight at all 4 sites. In fact, LCH dropped from 70 to 69 at 11:45 pm. So the streaks ended as follows... LCH - 148 days BPT - 146 ARA - 125 LFT - 124 PREV DISCUSSION... /issued 347 AM CDT Thu Oct 11 2018/ DISCUSSION...Tropical Storm Micheal continues to quickly move northeast across the southeast states this morning while a cooler air mass spills into the northern gulf coast. The cooler air mass has allowed areas along I-10 to fall below 70 which is the first morning for most stations since mid May to early June and ending the record streak. Aloft, a long wave trough covers the west 2/3 of the lower 48. This trough is also helping to steer Tropical Storm Sergio in the Pacific toward Baja California. Today through Saturday dry conditions are expected with near normal temperatures. Late in the weekend the remnants of Sergio from the Pacific will move across Texas, Oklahoma, and Arkansas while merging with a front. A few showers or storms will be possible across much of the area as moisture from system moves through. Higher rain chances are expected Monday as a short wave drops southeast across the plains and a cold front moves through. A cooler air mass will move back in after a brief warm up, however a few dreary days can be expected as overrunning occurs post front. Below normal temps may also occur during the middle of next week which hasn't occurred in the area since early September while the area saw a string of wet days. MARINE...Marine conditions continue to improve has high pressure settles and an Micheal departs the region, however small craft should continue to exercise caution in the gulf waters this morning. A moderate offshore flow will gradually relax Friday. Winds will become onshore again Saturday night and increase as low pressure moves across TX and OK. The pressure gradient will relax Monday as a front enters the area, however offshore winds will increase Tuesday as high pressure rebuilds into the north gulf coast. && .PRELIMINARY POINT TEMPS/POPS...
