What forecasters said that day
The local office's own words before this heat advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Twin Cities, MN wrote its last area forecast discussion before this heat advisory went out at Jul 25, 1:03 PM CDT, 1 hour 20 minutes earlier.
Area forecast discussion, Jul 25, 1:03 PM CDT, 1 hour 20 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 103 PM CDT Tue Jul 25 2023 .DISCUSSION...(Today through Monday) Issued at 352 AM CDT Tue Jul 25 2023 KEY MESSAGES: - Scattered severe Thunderstorms moving in from from west to east evening and overnight. Wind and hail the primary threats. - Dangerously hot conditions midweek with a chance for storms. Forecast heat indices around 100 Wednesday and Thursday. Any thunderstorms that develop could be strong to severe, but also limit afternoon heating. - Temperatures cool back down closer to normal this weekend into next week. Today and tonight...Today will be hot, with afternoon temperatures and heat indices in the mid 90s. Later this evening scattered thunderstorms will move in from the Dakotas and track across the region. A few storms could be severe, with wind and hail as the primary threats. Early morning satellite imagery with radar and surface obs showed a few scattered storms across western Wisconsin, but these should dissipate later this morning. For the rest of the day, skies will be mostly clear with some filtered sunshine from smoke and cirrus. Southerly winds will develop and afternoon highs will reach the mid 90s for many locations. Dewpoints will be in the low to mid 60s, which will keep heat indices near the actual air temperatures. Later this afternoon, showers and thunderstorms will develop across the eastern Dakotas as a shortwave trough moves through. Given the large amount of instability, these storms should intensify quickly and move east/southeast during the evening and overnight hours. The track and coverage of these storms is still uncertain, but have increased the likelihood of rain to above 50/50. These storms could produce severe weather as they ride the CAPE gradient, and SPC has a slight risk across western Minnesota, with a marginal risk extending eastward toward I-35. The overall set up is rather favorable for a severe MCS to track through the region, so this will certainly be something to monitor throughout the day. Hail and wind are the primary threats Wednesday through Monday...Heat will be the main story, but the back story will be the potential for thunderstorms. As temperatures warm Wednesday and Thursday, dangerous heat will be possible both days with heat indices near or slightly above 100 degrees possible. However, as has been the case leading up to this event, any thunderstorms that develop could limit the amount that temperatures warm during the day. For that reason, continued with a blended guidance for both highs and lows. Currently is appears that Tuesday night's convection will exit the region and allow temperatures to warm on Wednesday. Another round of storms is possible on Thursday, but these might hold off until the late afternoon and evening, which could lead to another dangerously hot day on Thursday as well. There is a marginal risk of severe weather across the region for late Thursday into Thursday night. Looking ahead, the rest of the forecast has higher uncertainty, as it will be dependent on the storms that form between now and then. In general, cooler temperatures will settle in across the region as weak cold front pushes through the region, but how far south that front makes it, and when it returns north as a warm front is still unknown. What is known is that this front will be the focus for continued showers and thunderstorms to end the month of July. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1255 PM CDT Tue Jul 25 2023 Big question this period is what happens with convection overnight. The wave currently approaching Bismark is what will spark convection this afternoon over NoDak, that will then follow the instability gradient southeast into MN. At this time, prefer a HopWRF solution for how things evolve, with an MCS heading down the upper MN River Valley from west central MN to north central Iowa this evening. This means RWF and MKT look to have the greatest risk of seeing storms. It's a closer call for MSP/AXN/EAU, with activity most likely to stay south of STC and RNH. KMSP...Current trends place the greatest TS potential south of MSP tonight, but the threat is still good enough to support the prob30 we had going, we just bumped up the timing by a couple of hours. /OUTLOOK FOR KMSP/ THU...VFR.
