Area forecast discussion, Mar 29, 6:34 AM CDT, 1 hour 39 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 634 AM CDT Fri Mar 29 2019 .DISCUSSION... The discussion for the 12Z TAF forecast can be found below. && .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. There will be a chance of thunderstorms this morning across NE OK and again late today and tonight with the cold front. A period of MVFR cigs is expected, with IFR cigs and showers expected late across NE OK behind the cold front. Lacy && .PREV DISCUSSION... /Issued 418 AM CDT Fri Mar 29 2019/ DISCUSSION... Early this morning a cold front stretched from a surface low over the Texas Panhandle through North Central Oklahoma...just northwest of Northeast Oklahoma...and into Northeast Missouri and Central Illinois. Along/near this boundary...warm air advection combined with elevated instability has allowed for isolated to scattered showers/isolated thunderstorms to develop from North Central Oklahoma into Central Missouri. This activity will continue to be possible through the morning hours as the frontal boundary looks to remain nearly stationary...just west and northwest of Eastern Oklahoma and Northwest Arkansas. Steep mid level lapse rates and elevated instability could aid in a couple storms becoming strong to marginally severe. The big obstacle for convection will be the strong cap in place over the region. The frontal boundary is forecast to get a push southeast this afternoon through tonight as an upper level wave...currently crossing the Southern Rocky Mountains...moves into the Central Plains. Scattered showers and isolated thunderstorms remain possible this afternoon/evening as the frontal boundary approaches/moves into the CWA. Again...convection will have to fight through a strong cap from a deep warm layer residing ahead of the front. However...any convection that can develop will have the potential to become strong to severe with large hail and damaging winds the main hazards. The greater potential for this activity looks to be over Northeast Oklahoma as the frontal boundary moves into the CWA this evening. Overnight tonight...the greater shower and thunderstorm chances look to shift east and southeast across the CWA with the movement of the cold front. The cold front looks to be exiting the region early Saturday morning with shower and isolated thunderstorm chances continuing behind the boundary Saturday morning before the mid level trof axis shifts east of the CWA Saturday afternoon. Behind the cold front...gusty northerly winds are forecast to spread over the region with Canadian surface high pressure dropping southeast into the Plains. The result will be high temperatures Saturday and Sunday only reaching into the upper 40s and 50s. These temperatures combined with the gusty northerly winds will create wind chill values in the 30s to mid 40s Saturday afternoon. Surface high pushes over the CWA Saturday night with clearing skies and subsiding winds. This will aid in temperatures looking to bottom out near/below freezing for parts of Northeast Oklahoma and far Northwest Arkansas Sunday morning. Near freezing temperatures could again be possible Monday morning over far Northwest Arkansas as surface begins to push off to the east. In the wake of the departing surface high...a shortwave looks to move through the Southern Plains Monday. A lack of moisture over the region should limit precip potentials...though a slight chance of a shower could be possible mainly south of Interstate 40. Southerly winds then return Tuesday with a warming trend into the second half of the week. Late in the week...another low pressure system looks to move into the Plains with additional chances for showers and thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
