Area Forecast Discussion National Weather Service Omaha/Valley NE 628 PM CDT Thu Jun 4 2020 ...Updated Aviation Forecast Discussion... .DISCUSSION... Issued at 325 PM CDT Thu Jun 4 2020 Today and Tonight: Temperatures and storms are again the forecast concern today. It appears about the entire forecast area should get to 90 degrees again. Most notably, dewpoint temperatures are slightly higher today which may make it feel hotter today. Storms are not likely in this area until 10 pm or so. The most likely area for storms would be north of a line from Columbus to Omaha. The environment is slightly better today than yesterday for sustaining storms, but it's still not great. Dewpoints in the north are right around 60 degrees and low level moisture is generally lacking. The lifting condensation level (LCL) and level of free convection (LFC) heights are still high. However, surface based CAPE values should reach about 2000 J/kg and deep layer shear will be near 45 to 50 knots. Storm development is likely in south central South Dakota or north central Nebraska. With a slightly more favorable environment, it's possible these storms carry into eastern Nebraska and western Iowa. After midnight, the environment becomes less favorable and storms should fall apart. Strong wind gusts and small hail would be the most likely threat from any potential storms. Friday, Saturday, Sunday: Over the weekend, the upper level ridge will strengthen over the central CONUS. That will lead to increased warm and moist air advection. Temperatures and dewpoints should slowly increase. Temperatures of 90 degrees are expected for the entire forecast area for the weekend. Looking at the wide range of the many model solutions, the CMC (Canadian, which has been verifying well lately with the warm temperatures), shows that 98 is with the realm of possibilities along the Nebraska/Kansas border. The dew point temperatures around 70 degrees, the heat index would be over 100 in those areas. I have been bumping up temperatures each day this week so it is trending in that direction. Saturday and Sunday will also feature strong winds from the south. Starting Saturday morning, sustained wind speed will be around 20 to 25 mph with gusts up to 35 mph. Storms are possible over the weekend, but the probability for them is low. Temperatures are gonna be hot and the winds are going to be strong. If our confidence increases in weekend storms, we'll include it more in the discussions and through weather stories. Monday through Thursday: The strong winds should carry over into Monday and finally come to an end that evening. Monday will likely be another warm day for the area with temperatures above 90 degrees expected. The overall pattern begins to change early in the week though as a trough should begin to move over the West Coast. This will slowly push the ridge off to the east and bring a relief from the hot temperatures. The trough and associated cold front will provide for a chance of thunderstorms likely Monday night or Tuesday morning. Complicating the extended forecast is tropical depression Cristobal in the Caribbean. It's possible it has an impact on the overall pattern over the CONUS. The general model consensus is that zonal flow dominates which would lead to normal temperatures (77 to 85) for the rest of the week. && .AVIATION...(For the 00Z TAFS through 00Z Friday evening) Issued at 619 PM CDT Thu Jun 4 2020 VFR conditions are expected for much of the TAF cycle. The exception will be with possibility of scattered convection overnight which is a possibility at all three sites. If thunderstorms do roll through the sites, gusty winds and hail in addition to heavy rain are all possible. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.
