Area forecast discussion, Jun 14, 3:00 PM CDT, 10 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 300 PM CDT TUE JUN 14 2016 .SHORT TERM.../Tonight/ Issued at 300 PM CDT Tue Jun 14 2016 Main concerns are severe storms and rainfall/flash flood potential. Cluster of storms beginning to fire northwest as upper level support increases through the evening hours. Surface boundary has become near stationary over northern Iowa and the focus for storms will be near the boundary over the next 3 to 5 hours. Expected evolution of storms...cold pool developing over the northwest with additional lines of storms moving into the boundary now. Expecting the are to congeal into a larger cluster near the boundary then begin to follow the instability axis east southeast with time this afternoon/evening tracking through the flash flood watch area through this evening. Will make no changes to the flood watch outline for now...as the far north is more likely to reach guidance criteria given previous rainfall than areas south of the watch. Per previous guidance... precipitable water increases to near 2 inches over the northeast by 00z with warm cloud depths above 10kft. Moisture transport increases into the boundary by early evening as well over the northeast. Generally 2 to 4 inch amounts are possible in any training or slow moving cells. Otherwise instantaneous rainfall rates will reach 1 to 2 inches per hour...so heavy downpours are likely with the passage of the storms. Overall the best chances for severe storms will remain across the north and quickly diminish between 00 and 06z as the entire system shifts to the east. By 00z the line/area of storms will generally be east of I35 with scattered activity over the south. Over the south some scattered severe thunderstorms will occur through 02z. Lows tonight will fall into the 60s to near 70 over the south. .LONG TERM.../Wednesday through Tuesday/ Issued at 300 PM CDT Tue Jun 14 2016 Fairly quiet mid/long range with a large upper level ridge building into the central US Wednesday into the weekend. This will allow for mainly sunny, dry and warming conditions into the weekend. H85 temps remain in the upper teens to low 20s Celsius which should continue to yield above average temperatures through the forecast period. Additionally as the heat builds beneath the ridge, may have to budge temps up a bit more. Ridge begins to dampen into the latter portion of the weekend into early next week. This will allow for some slightly cooler temperatures and a return of storm chances. A boundary will become stalled out across the state toward the end of the period, therefore expect the possibility of a more active period toward next week and beyond the current forecast period. Guidance grids try to bring in precip chances by late Saturday into Sunday, however feel they are breaking down the ridge a bit fast so therefore did lower a bit and cut back on the coverage as feel best chances for precip look to be toward Monday and Tuesday. && .AVIATION.../For the 18Z TAFS through 18Z Wednesday afternoon/ Issued at 300 PM CDT Tue Jun 14 2016 Main concerns will be storms progressing across the region this afternoon and evening. Generally the storms will track east southeast along the warm front with a period of storms between 20z to 01z with potential for brief +TSRA with wind gusts to near 45 kts. The sites most likely to be affected include KFOD, KMCW, and KALO. Brief MVFR conditions will also occur...though vsby may drop to IFR in some of the heavier storms as they move quickly to the east this evening. Storms will exit the east near 06z with quiet conditions remainder of the period. && .DMX Watches/Warnings/Advisories... Flash Flood Watch until 1 AM CDT Wednesday for Bremer-Butler- Cerro Gordo-Emmet-Franklin-Hancock-Kossuth-Palo Alto-Winnebago- Worth-Wright. && SHORT TERM...REV LONG TERM...Beerends AVIATION...REV
