Area forecast discussion, Aug 12, 5:33 PM CST, 1 hour 12 minutes before
Area Forecast Discussion National Weather Service Dodge City KS 633 PM CDT Mon Aug 12 2019 ...Updated Aviation Discussion... .SYNOPSIS... Issued at 312 PM CDT Mon Aug 12 2019 West-northwesterly mid to high level flow will persist through Saturday. A frontal boundary will be situated along the southern edge of the westerlies, with ample moisture and upslope flow on the cool side near I-70. Given the westerly flow across the Rockies, a surface trough will extend south from the low across the southern high plains. By Sunday, upper level ridging will strengthen again across the central high plains, with the westerlies lifting north into the northern plains. && .SHORT TERM...(This evening through Tuesday) Issued at 312 PM CDT Mon Aug 12 2019 A weak surface front was located along the southern counties with Oklahoma this afternoon. A few thunderstorms will persist along this boundary through about 9 pm before moving father south into Oklahoma. By Tuesday evening, upslope southeasterly flow is expected to develop across the plains, with an area of surface convergence in extreme northeastern Colorado. Thunderstorms will develop in this convergence with surface heating and propagate southward and southeastward into western Kansas in the evening. The storms will be severe with large hail and damaging winds in the evening, especially before reaching as far south as I-70, then gradually decrease in severity during the late evening and overnight. It is uncertain how this storm cluster will track; but the most favored area for now is from Scott City southward to Garden City and Meade. High winds and heavy rain may be a concern into the early morning hours Wednesday in places like Garden City, Ulysses and Liberal. If the storm cluster is father east then Dodge City and Jetmore could receive heavy rain as well. .LONG TERM...(Tuesday night through Monday) Issued at 312 PM CDT Mon Aug 12 2019 Another cluster of thunderstorms is expected Wednesday evening in a similar setup. Much of western and central Kansas has a chance of thunderstorms Wednesday night. The same pattern will hold through Friday, with the best storm chances shifting north to around Interstate 70. But the aforementioned upper level ridge should suppress rainfall over the weekend to a more isolated basis. In general, temperatures will continue to be warmer along the Oklahoma state line and cooler near I-70. && .AVIATION...(For the 00Z TAFS through 00Z Tuesday evening) Issued at 619 PM CDT Mon Aug 12 2019 Scattered thunderstorms will be possible over the next few hours near the Oklahoma border which will include the Liberal area. Wind gusts in excess of 35 knots is not completely out of the question with these storms. Bufr soundings indicate mainly lower VFR ceilings through 03z Tuesday at Liberal. VFR conditions can also be expected across western and north central Kansas early Tonight. Winds tonight outside the thunderstorms will be northerly at less than 10 knots. RAP and NAM soundings do suggest that there will be an increase in moisture in the 2000 to 3000 ft AGL level at Dodge City, Garden City and Hays after 09z Tuesday. This may produce some scattered ceilings around daybreak in the MVFR category. Any clouds that do develop late tonight will erode by 15z Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
