Area forecast discussion, Sep 1, 11:04 AM CDT, 4 hours 14 minutes before
Area Forecast Discussion National Weather Service Norman OK 1104 AM CDT THU SEP 1 2016 .UPDATE... Lowered high temperatures/decreased probabilities of thunder this afternoon. && .DISCUSSION... Expect broken to overcast skies to continue into the afternoon as 925-700 mb relative humidity are progged to stay nearly saturated through the period. Consequently, lowered high temperatures this afternoon. Locations in central and northern Oklahoma will likely stay seasonably cool in the 70s--around 15 degrees below average. As a result, also opted to decrease the probabilities for thunder (only included isolated thunder) across central/northern Oklahoma as the greater MUCAPE will likely be across southern Oklahoma and western north Texas this afternoon. Mahale && .PREV DISCUSSION... /issued 620 AM CDT THU SEP 1 2016/ AVIATION... Developing showers and storms will become more widespread this morning, impacting most TAF sites at some point today. Do to the scattered nature of these storms, there is some uncertainty in the timing, though in general convection should spread southeastward through the day. Intermittent IFR ceilings should lift to MVFR and VFR by mid morning. Day PREV DISCUSSION... /issued 323 AM CDT THU SEP 1 2016/ DISCUSSION... One last shortwave and weak front associated with the Great Lakes trough is set to push through the region today, which combined with the abundant moisture present will bring scattered to widespread showers and thunderstorms. Possible impacts include heavy rainfall leading to flooding and strong wind gusts, though weak shear should keep storms from becoming severe. After this shortwave leaves the area, a surface high builds in to the northeast, bringing drier air in and limiting precip chances over the next few days. Temperatures gradually warm back up to the low to mid 90s. Saturday and Sunday may see a slight chance for some precip in our western counties as a shortwave associated with the next trough moves through, but moisture will be limited and forcing from the trough look to be weak. Outside of this, generally dry weather will continue until Tuesday as the northwest trough begins to move in. As the northwest upper low moves in, low rain chances return to the area mid to late week next week. Day && .PRELIMINARY POINT TEMPS/POPS...
