Area forecast discussion, Jun 15, 6:36 PM CDT, 1 hour 26 minutes before
AREA FORECAST DISCUSSION National Weather Service Hastings NE 636 PM CDT Tue Jun 15 2021 ...Aviation Update... .DISCUSSION...(This evening through Tuesday) Issued at 323 PM CDT Tue Jun 15 2021 Cirrus from earlier convection continues to thin across the western part of the area this afternoon. A surface high pressure system across the area is keeping the winds light and somewhat variable. The upper level ridge continues across and to the west of the area tonight through Thursday. Temperatures are expected to remain on the warm side. Wednesday a surface low and cold front start to develop to the northwest of the forecast area. This will keep south winds across the area which will increase to 15 to 20 mph. Moisture will increase on the south winds and the higher dew points are expected to increase the heat index values to a few degrees on either side of 100 degrees. By Thursday, the cold front starts to work into the forecast area, but is not as strong and the temperatures are not expected to be much cooler. They will be a bit cooler in the north, but a little warmer in the south. The difference will be that the dew points will be a little lower and the heat index could actually be lower. Thursday night, the front will move to the south of the forecast area and there is an upper level wave that moves over the ridge. Models have a few differences in the location of the weak front and the precipitation that is possible. Have kept some low PoPs for much of the area. Friday through Tuesday the ridge broadens and the flow across the area becomes more zonal. There are a few waves that move through the area and there will be some more thunderstorm activity. At this time, the strongest wave and best chance for thunderstorms appears to be Saturday night. Otherwise, there will be on and off chances for thunderstorms. The models have a few differences, but most of the systems seem to be more during the night-time. && .AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Thursday) Issued at 635 PM CDT Tue Jun 15 2021 General overview: Overall, another high-confidence VFR ceiling/visibility forecast, with the main difference being slightly-stronger wind speeds compared to these past 24 hours (especially Wednesday afternoon). Details: Assuming that no isolated/sneaky convection manages to bubble up directly over the area between now and nightfall/roughly 02-03Z, (currently considered no more than a 5-10 percent chance and thus not included in TAFs), this should be another straightforward and dry/storm-free aviation period with minimal mid-high cloud cover at most. As for surface winds, they will average no more than 08-10KT this evening-overnight, generally averaging from a southeasterly direction. However, speeds pick up a touch during the day Wednesday, with sustained southerly speeds around 15KT/gusts around 20KT common, especially 17-23Z. On one last wind-related note: There are hints of weak-ish low level wind shear (LLWS) especially 10-14Z as winds mainly between 500-1,500 ft. increase to 25-30KT from the southwest. However, with overall-shear magnitude looking to only average around 25KT, this looks a bit marginal for formal TAF inclusion. Something for later forecasts to keep an eye on though. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE. KS...NONE. && DISCUSSION...JCB AVIATION...Pfannkuch
