AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 228 AM CDT Wed Jul 15 2020 .Discussion... Issued at 228 AM CDT WED JUL 15 2020 A cold front with a line of showers and thunderstorms is expected to move south into the Kansas City metropolitan area early this morning. Rainfall rates and precipitable water values continue to be impressive with early totals exceeding 1.5-2 inches of rain. Our primary concerns are flash flooding and strong winds as this system makes it way into more urbanized areas. Expected time of arrival for the KC area is between 4 and 7AM. The wide range of the temporal estimate are a result of uncertainties in the intensity of rear inflow into the line and how it will maintain its structure as it moves south. It is anticipated as the line of storms moves south, it will begin to interact with the large precipitation complex in central KS. The primary effect of this interaction is storms gaining a large eastward movement eventually being carried out east by the entire complex. The line is expected to sink to around the I-70 corridor by sunrise before turning east. Do not worry about missing the rain for those in the southern portion of our CWA. The large complex in central KS will move into the moisture rich environment of western MO bringing some showers and thunderstorms. Precipitable water values exceed 2 inches for much of the Kansas City area. This means that storms will be very efficient when it comes to rain production. As a result flooding on roadways, parking lots, and other impervious surfaces is likely. Urban small streams will also see rapid rises and falls as water runs off from urban structures. Please travel safely and remember to turn around when you see a flooded roadway. Clouds and rain are expected to hang around for much of the day today. The good news (besides the much needed rain) is that temperatures will be much cooler with highs only in the mid to upper 80s. Sure, it is going to be cloudy and rainy, but it will not be hot at least. However, the reprieve will be short lived as by Friday, a surface high pressure parks over SE NE and N KS clearing our skies enabling the sun to heat the area up almost unimpeded. Unfortunately, the baking quickly resumes as temperatures accelerate to the mid 90s on Friday culminating near 100F during the day Sunday. Mid-90s highs are expected to continue into next week. && .Aviation...(For the 06Z TAFS through 06Z Wednesday Night) Issued at 203 AM CDT WED JUL 15 2020 A cold front gradually sagging southward across northern Missouri and northeastern Kansas has initiated a line of thunderstorms with heavy rain this evening and overnight period. As the surface cold pool continues to strengthen along this line of storms, the storms will quicken their pace south and impact the terminals between 08-12Z with rain showers and thunderstorms possibly continuing through 18Z. KSTJ will be the first to see thunderstorms as the line shifts southward. VFR ceilings will lower to low VFR or MVFR as the storms approach. As thunderstorms move over the terminal, heavy rain will drop visibilities into the 1-3SM range with ceilings further dropping to 1-2kft. Southeasterly to easterly winds will shift to north-northwesterly behind the front. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...CDB/Pesel Aviation...PietrychaP
