Area Forecast Discussion National Weather Service Omaha/Valley NE 632 PM CDT Wed Jun 3 2020 ...Updated Aviation Forecast Discussion... .DISCUSSION... Issued at 148 PM CDT Wed Jun 3 2020 Today and Tonight: Temperatures are warming greater than expected today. Where as yesterday, 90 degrees didn't seem likely, it appears a few locations are at or will reach 90 or above. The forecast concern again will be the possibility of evening and overnight storms. There is a good amount of lower atmosphere mixing which will make storm development in eastern Nebraska difficult. The dewpoint temperatures are not favorable for storm development leading to high LCL (lifting condensation level) and LFC (level of free convection) heights. If the area is to see storms, it'll likely develop to the west and move into the area. Current radar imagery shows severe storms in south central South Dakota and north central Nebraska. Those storms are associated with a mid-level shortwave currently located over South Dakota. The GFS/HRRR show 500 mb height falls increasing over northeast Nebraska which would move those storms that direction and provide enhanced lift. An analysis of the surface shows a drop in surface pressure over the past 3 hours. The instability in that region should be around 1000 J/kg which could lead to a few storms with strong wind gusts as the most weather threat. Another possible area for severe weather will be in the far southeast counties in Nebraska. Storm development is likely to start in central Nebraska. Convective Allowing Models (CAMs) show storm development around 6 PM with storms moving southeast. The concern is that a mesoscale convective scale system (MCS) will develop. If that is realized, 50 to 60 mph winds across the southern counties are the most likely storm threat. Small hail and periods of heavy rain are also in the realm of possibilities. Similar to yesterday, the collective of the CAM models don't provide much confidence as they offer a wide range of solutions. The thing to look for will be storm development in that 5-7 PM window. If we don't get anything by then, the environment will become less favorable. Thursday: Temperatures and dew point temperatures will be slightly higher due to strong virtual temperature advection. This will greatly increase the instability across the area and surface based CAPE values are expected to be over 3000 J/kg. Deep level shear is expected to be in the 40 to 45 knot range. This is an environment primed for storms, but there needs to be a trigger to set them off. With a strong elevated mixed layer, it is unlikely daytime heating alone can lead to convection. Another weak mid-level disturbance is expected to move through South Dakota. The latest model runs have kept that disturbance farther north. As such, the SPC has moved the slight severe risk farther north. Most of the area is now in a marginal risk, except far northeast Nebraska (Norfolk and north) which is still in the slight risk. Tornadoes, hail, and strong winds are the potential severe weather threats. Friday through Tuesday: There are some slight chances for thunderstorms and rain on Friday and Saturday. Sunday through Tuesday should remain dry. Temperatures for the weekend should be near 90 (plus or minus a few degrees depending on your location). The upper level ridge is expected to strengthen Saturday and Sunday so those days could be warmer than what is currently in the forecast. Medium range guidance is in good agreement in moving a trough over the West Coast which should push slowly push the ridge over the East Coast. This would provide a relief from the warmer temperatures on Tuesday (high temperatures ranging from 74 to 83 degrees). However, the pattern does become a bit complicated with tropical storm Cristobal. Depending how that storm develops and the direction it moves, it could have an impact on the overall upper level pattern over the CONUS. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 626 PM CDT Wed Jun 3 2020 Radar mosaic currently showing a line of TSRA roughly from KONL to KLBF moving to the southeast. Expect northern flank of activity to move into KOFK around 02Z and KOMA/KLNK around 04Z. The line of storms should be clear KOMA/KLNK then shortly after midnight. VFR conditions prevail then the remainder of the forecast period. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && DISCUSSION...Fajman AVIATION...DEE
