Area forecast discussion, Jun 12, 5:48 AM CST, 47 minutes before
Area Forecast Discussion National Weather Service Norman OK 648 AM CDT Fri Jun 12 2020 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 313 AM CDT Fri Jun 12 2020 Deep, weak warm advection within relatively moist layer atop modest low level jet has lead to numerous showers early this morning from southwest Kansas into northwest Oklahoma. The kinematics are primarily driven by weak s/wv trough progressing southeast through central KS as evident on water vapor imagery. Very shallow and elevated instability layer has yielded enough vertical motion for charge separation resulting in scattered lightning strikes. This activity should weaken and slowly dissipate through the morning. We will also add mention of low shower/thunderstorm chances across extreme northwest Oklahoma for this evening as late day scattered rain activity progd for the Panhandles and far southwest Kansas (near weak surface trough) could move into the body of Oklahoma before dissipating. For this afternoon, hot and dry conditions combined with gusty south winds will yield continued elevated fire weather conditions. Despite rain activity this morning, which for the most part is light, fine fuels will still be in play this afternoon. A fire danger statement will be issued for this afternoon. && .LONG TERM... (Saturday through Thursday) Issued at 313 AM CDT Fri Jun 12 2020 Overall, little change to the going extended forecast. Highs this weekend and next week will remain about 5 to 10 degrees above average, while low temperature forecasts will be closer to average at most locations. This trend will continue to yield elevated fire weather conditions during the afternoons as fine fuels continue to dry and become dormant, especially across the western half of Oklahoma and adjacent parts of northern Texas where winds will be stronger. Medium range models differ on western/central U.S. trough progression late next week and next weekend. GFS more progressive with at least a shot at rain for the region. The ECM...not so much. && .AVIATION... (12Z TAFS) Issued at 639 AM CDT Fri Jun 12 2020 Showers and thunderstorms that are currently near KWWR and KPNC will possibly continue over the next few hours. Went ahead and put showers for KOKC and KOUN through about 13Z, though there is uncertainty as to whether rain will reach the ground before evaporating from the high cloud bases. Scattered high clouds will be possible throughout the period with VFR conditions. Thompson && .PRELIMINARY POINT TEMPS/POPS...
