Area forecast discussion, Jul 3, 2:51 PM CDT, 2 hours 16 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 251 PM CDT Tue Jul 3 2018 .DISCUSSION... Scattered showers and thunderstorms continue to propagate slowly south and west this afternoon in moist/unstable air-mass on north side of easterly wave. A few of these storms could produce gusty winds with locally heavy rainfall likely in the stronger cells. Storms will begin to dissipate early this evening with loss of surface heating. Heat advisory remains in effect for most of eastern Oklahoma and west-central Arkansas through this evening with heat indices in the 105 to 110 degree range this afternoon. Although hot/humid conditions will persist on Wednesday, should see a modest increase in cloud cover with slightly drier air which should keep most areas at or below 105 for heat index values Wednesday afternoon. Scattered storms will again be possible across SE OK on Thursday as upper high begins to shift back westward. This will allow a weak backdoor cold front to move through the area on Friday with a continued chance of storms. Drier air will filter into the region behind front over the weekend with precipitation chances shifting south of the area. && .PRELIMINARY POINT TEMPS/POPS...
