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 May 26, 12:16 PM CDT, 2 hours 8 minutes earlier.
Area forecast discussion, May 26, 12:16 PM CDT, 2 hours 8 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 1216 PM CDT Sat May 26 2018 .UPDATE... Issued at 1209 PM CDT Sat May 26 2018 Updated to include 18z aviation discussion below. && .SHORT TERM...(Today and tonight) Issued at 405 AM CDT Sat May 26 2018 Upper level ridging begins building into the region today, but a shortwave trough will continue traveling eastward through Southern Saskatchewan with weak vorticity over Northern WI. As a result, the NAM, HRRR, and other hi-res models develop convection this afternoon in the Eastern WI counties of the CWA. MUCAPE values are forecast to reach near 1500 J/kg and effective bulk wind shear should reach near 30 kts. So, there is a possibility for some isolated strong updrafts and a few strong wind gusts and hail. Otherwise, the bulk of the thunderstorm activity should occur to the east and north of the CWA. Another concern for the Memorial Day Weekend is the unseasonably warm temperatures. Mostly clear skies and diurnal heating will allow mixing through about 700 mb by late Saturday afternoon. This will allow temperatures to reach the lower to mid 90s with the warmest temperatures expected on the Buffalo Ridge. A few record high temperatures for May 26th may be broken. The record highs are: 96 at MSP (1978), 93 at STC (1914), and 93 at EAU (1914). Relative humidity will be lower than Friday as values are expected to drop into the upper 20s to lower 30s with dewpoints in the 50s. Thus, heat index values are not expected to differ very much from the temperatures. Westerly winds will be near 5-10 kts during peak heating. Then, temperatures overnight into Sunday are anticipated to fall into the 60s with the TC metro being closer to 70 degrees. .LONG TERM...(Sunday through Friday) Issued at 405 AM CDT Sat May 26 2018 The heat builds on Sunday, with relief not expected until the last half of the upcoming week when shower and thunderstorm chances also return. The omega block will be fully in place on Sunday, with mid/upper ridging reaching its peak. At daybreak, there looks to be the potential for nocturnally-driven convection over the Dakotas to be knocking on the doorstep of western MN, per NSSL-WRF and NAMnest solutions. Have included a small area of 20-30 POPS over west central MN, but may need to expand this area spatially if the signal proves to be consistent. H85 temps look to moderate to around +22C on Sunday afternoon. Other than a few cumulus clouds, ample sunshine will combine with southerly winds and mixing to 700-750mb. Model guidance has come in a bit warmer than previous runs, thus giving more credence to the potential for highs from 90-100 degrees. Dewpoints will also be up around 60 degrees, which will push heat indices close to advisory criteria. Will continue to monitor trends, but a heat advisory is a strong possibility for Sunday. Still have reservations about an entirely dry forecast for Sunday, given progged 700mb temperatures are only around +10C, which is borderline as far as a CAP is concerned. There won't be much in the way of a triggering mechanism provided any ripples of energy topping the ridge stay north, but wouldn't be surprised if instability proves sufficient to yield pop-up, isolated activity. Sunday night into Monday the low over the Great Basin begins to progress eastward. Warm/moist air advection ahead of this feature noses into central MN/WI on Sunday night. Have included 20-30 POPS primarily along/north of Interstate 94, with any activity expected to wane Monday morning. More widespread shower and thunderstorm activity is expected late Monday night through Wednesday as the aforementioned low ejects across the area while weakening. After that, we look to be dry overall to finish the week, with more tolerable highs in the mid 70s to mid 80s. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1209 PM CDT Sat May 26 2018 VFR conditions are forecast for this period. Aside from a few passing high clouds this afternoon, SKC conditions are expected. Westerly winds will increase to near 10 kts this afternoon then become light overnight into Sunday then pick up from the southeast to south near 10 kts. KMSP... No concerns. /OUTLOOK FOR KMSP/ MON...VFR. Wind S 5 kts. TUE-WED...Mainly VFR. Chc -SHRA/-TSRA. Wind SE 5-10 kts. THU...VFR. Wind NW 5-10 kts. && .MPX WATCHES/WARNINGS/ADVISORIES... WI...None.
