Trent Posted July 20, 2011 Share Posted July 20, 2011 This is what happens when 3.5" of rain falls overnight and you get a lake breeze. Full sun this afternoon with highs in the upper 70s, albeit still extremely humid. Just 74 degrees when I got home from work. I'm afraid to see what kind of dewpoints/heat index combos we get here once winds become off shore and the 90s flood in. Link to comment Share on other sites More sharing options...
MN Transplant Posted July 20, 2011 Share Posted July 20, 2011 I have to wonder if some of those crazy high DPs in the Dakotas and MN are due in part to this. Almost certainly so. I imagine that some of the daily readings are also affected by immediate rainfall, like the Moorhead reading after a storm overnight. Given the ridge, I bet we'd be talking about extreme temperatures instead of record DPs if it had been dry instead. Link to comment Share on other sites More sharing options...
MN Transplant Posted July 20, 2011 Share Posted July 20, 2011 I have to say that seems a bit suspect. Fargo is right across the river and it was only at 80. Wind off of an ag field vs wind off of a city neighborhood. Plus they had a bunch of rain overnight in that immediate area. But yes, anytime you see that big of a difference it raises a question. edit - more digging Each station in Fargo, including Hector, is above 82 now. A road station near the Moorhead site is obviously broken, but another at the river has an 87 DP. Link to comment Share on other sites More sharing options...

Although it would be tough to challenge a lot of those record temps from the 1930s in the Dakota, MN, IA, NE, IL, etc. Definitely would need drier, "Dust Bowl" type conditions.

OceanStWx Posted July 20, 2011 Share Posted July 20, 2011 I have to say that seems a bit suspect. Fargo is right across the river and it was only at 80. You have to watch the ASOS/AWOS sometimes too. The AWOS stations don't have quite the same preventative maintenance schedule, nor are the dewpoints considered all that important to go fix if reading high or low. But seeing the dewpoints posted at Davenport, Moline, Fargo and Minneapolis (among others I'm sure) are totally legit 80s. Link to comment Share on other sites More sharing options...

AOMC is all over the ASOS when things go wrong ...I know AWOS doesn't get the same treatment. Mainly why I believe the Fargo ASOS but not the Moorhead AWOS.

Yeah, and of course as I say that I notice Fargo was at 83 last ob. But yeah, atrociously humid. That is about as hellish as it gets. I hate dewpoints higher than 60, 80s is just horrific.

Powerball Posted July 20, 2011 Share Posted July 20, 2011 00z NAM still has 2m temps in the lower 100s for Detroit on Thursday. We could also have our first official 80*F day low Wednesday night/Thursday morning. Quite of bit of moisture and instability too. It looks like we would get into those 110*F heat indices if we actually had that type of moisture. Weekend's looking iffier though. It's like every run the GFS and EURO switch their masks with each other (when one shows one thing the other shows another and vice-versa). There's no large scale diferences, but it would mean the difference between lower/mid 90s and mid/upper 80s Friday through Sunday or Monday. This is minus any convection as well.

michsnowfreak Posted July 20, 2011 Share Posted July 20, 2011 Will be interesting to see if DTW can hit 100F on Thursday.

BowMeHunter Posted July 20, 2011 Share Posted July 20, 2011 Dam lake breeze today is going to screw us out of all this heat even attaining heatwave status if we can't pull a 90 Friday, still not giving up hope on Friday tho. Prob going to have more 90's this month than the last 2.5 summers combined. Link to comment Share on other sites More sharing options...
BowMeHunter Posted July 20, 2011 Share Posted July 20, 2011 Da fook, LAF - 97? Down sloped all that heat from the w/nw lol? I figured I had about a 10% chance of winning today. Link to comment Share on other sites More sharing options...

BowMeHunter Posted July 20, 2011 Share Posted July 20, 2011 ORD had a low of 78 early this morning. If it holds, this would tie the record high min set back in 1977. Bummer.. it was 81 I think when we got home from the casino and I looked at 5am. Link to comment Share on other sites More sharing options...
Hoosier Posted July 20, 2011 Share Posted July 20, 2011 ORD ended up topping out at 93 today. Will be interesting to see what happens with the storms. If ORD gets deluged overnight it could conceivably knock a degree or two off of the high. Link to comment Share on other sites More sharing options...
snowlord81 Posted July 20, 2011 Share Posted July 20, 2011 Will be interesting to see what happens with the storms. If ORD gets deluged overnight it could conceivably knock a degree or two off of the high. Are we going to have to deal with cloud debris again? That would be the 3rd morning in a row. If we could avoid it I bet KIND could top out near 98-100 Wed/Thurs/Fri. Even with the clouds around we have easily made it into the low 90's. This morning at my home weather station it was 92F and 83F on the dew with overcast skies! Of course I live by a forest and corn fields are all around.

Tomorrow will probably a bit low with 98-100 more likely...Unless the Wisconsin MCS makes it down here with some rain, then only mid-90's. Link to comment Share on other sites More sharing options...
Stebo Posted July 20, 2011 Share Posted July 20, 2011 I have figured out what it feels like outside, It feels like a bathroom after someone had a hot shower. Interestingly enough its actually cooler tonight than it was last night at midnight, however it is more humid, so the temp shouldn't drop much more.

BowMeHunter Posted July 20, 2011 Share Posted July 20, 2011 what I wouldn't give to be up north this week. These are the kind of weeks you dream of when putting your summer cabin reservation in.. to often than not its miserably chilly with front after front rolling through. 72/70 with calm winds up there.. Can just picture sitting on the pier casting a top water bait, drinking a beer and being scared poop less that a bat would fly in to me. Link to comment Share on other sites More sharing options...
