Powerball Posted August 21, 2013 Share Posted August 21, 2013 Today was how summer days should be. Temps in the mid 80s, dewpoints around 60*F, and hazy sunshine without the stratocumulus crap, just puffy afternoon cumulus clouds. The only thing missing were the popcorn t'storms.

Geos Posted August 21, 2013 Author Share Posted August 21, 2013 86° for the high today here. Dewpoints mixed out as the day went on. GFS taking some of the rain away in the 96 hour time frame. Link to comment Share on other sites More sharing options...

Enjoy it, the scenery is wonderful, though the lifestyle sure seems different, in many ways seems like it would be similar to the South. They love their four wheelers and country music.

It's nice to get a way from the city for a few days but I couldn't imaging myself living up there. At least the weather seems to always cooperate when I'm up there.

Man, just a turrible last 2 summers for you chasing. At least last summer you had the heat to get off to, Naso much this yr. About time for some heat as its been over a month since the last little and only bout of it we've had this whole summer and some lakes were really starting to cool down to the lower 70's. Couldn't script a better time for a little heat to come back than the last third of the month heading in to big Holiday weekend. Just perfect timing for those of us enjoying the Wisconsin lakes comfortably for the last time this season until next June. Days are really getting noticeably shorter.. dam near pretty dark not much after 8pm and thankfully we have another 10 months until that nonsense of the sun rising at around 5:10.

hawkeye_wx Posted August 21, 2013 Share Posted August 21, 2013 Latest Euro is the hottest run so far, would be 90s all next week for many, especially DLL and me on the western edge of the subforum. I can't say I'm looking forward to that. Might see "severe" drought popping up in Iowa by the end of that stretch. Link to comment Share on other sites More sharing options...
TimChgo9 Posted August 21, 2013 Share Posted August 21, 2013 This mornings 06z GFS shows the heat building in through the end of next week. 90's perhaps? Looks like mid 90's for Iowa, and 100's for the Plains? Also, looks mostly dry through hour 216. Man, I hope that moderates. Kids are not happy that their first day of school (today) is going to be 91 degrees. Link to comment Share on other sites More sharing options...

There is a breeze kicking up outside... maybe the air quality won't be so bad today. For anyone not liking the heat - take a look at Barrow, AK. It looks like they have a slight dusting of snow. http://seaice.alaska.edu/gi/observatories/barrow_webcam Link to comment Share on other sites More sharing options...
daddylonglegs Posted August 21, 2013 Share Posted August 21, 2013 90F yesterday and just about there again today... Euro looks nasty next week..especially west Kids here don't go back to school until after labor day, so hope the heat retreats by then... Link to comment Share on other sites More sharing options...

Chicago Storm Posted August 21, 2013 Share Posted August 21, 2013 Man, just a turrible last 2 summers for you chasing. At least last summer you had the heat to get off to, Naso much this yr. lol wut. Chase season is generally April to mid-June. Mid-late May was awesome, and there was a day in June. Then there was some local photogentic opportunity following the heat wave in mid-July.

Geos Posted August 21, 2013 Author Share Posted August 21, 2013 Tagged 90° now. Really hazy and breezy out now. Imagine the air quality is improving due to winds around 20 mph. LOT T-storm disco: IT APPEARS THAT SOME OF THESE DISTURBANCES MAY COMPLEMENT SOME OFTHE MODEST FRONTAL SCALE FORCING/MOISTURE CONVERGENCE ALONG AND NEARTHE FRONTAL BOUNDARY TONIGHT TO HELP KEEP AT LEAST SOME WIDELYSCATTERED TO SCATTERED STORMS GOING ACROSS THE AREA TONIGHT.ALTHOUGH THE THREAT FOR SEVERE STORMS WILL BE VERY LOW...THERE COULDBE A FEW GUSTY WINDS WITH SOME OF THE STRONGER STORMS.

Might see negative departure days that were previously looking hot. sdadasd.jpg Actually subsequent runs of the GFS and ECMWF show the potential for 90s next week. DTX agrees.... "H5 HEIGHTS IN THE 585-588DM RANGE AND H85 TEMPS NEAR 20C, THE POTENTIAL FOR HIGHS TOREACH INTO THE 90S WILL EXIST ON BASICALLY ANY DAY FROM MONDAY ONWARD." http://forecast.weather.gov/product.php?site=DTX&issuedby=DTX&product=AFD&format=CI&version=1&glossary=1 Link to comment Share on other sites More sharing options...
Chicago Storm Posted August 21, 2013 Share Posted August 21, 2013 LOT regarding Sunday and beyond... THIS COOL DOWN WILL BE VERY SHORT LIVED...HOWEVER...AS THE SURFACEHIGH QUICKLY SHIFTS EASTWARD. ONCE THIS OCCURS...A VERY WARM AIR MASSIS EXPECTED TO DEVELOP ACROSS THE PLAINS AND THEN SHIFT EASTWARDACROSS THE AREA LATER THIS WEEKEND AND INTO...AT LEAST...THE MIDDLEOF NEXT WEEK. THE MODEL GUIDANCE IS FORECASTING A CLASSICMID/UPPER-LEVEL DOME OF OF HIGH PRESSURE...WHICH LOOKS TO ENCOMPASSMUCH OF THE CENTRAL CONUS. THIS SHOULD RESULT IN A DRY WEATHERPATTERN AS THE MAIN STORM TRACK/RIDGE RUNNERS REMAINING WELL NORTHOF THE AREA. THE MAIN STORY WITH THIS WEATHER PATTERN WILL BE THEVERY WARM TEMPERATURES...ESPECIALLY SUNDAY THROUGH AT LEAST TUESDAY.GUIDANCE CONTINUES IN GOOD AGREEMENT WITH PROGGED 850 AND 925 MBTEMPERATURES OF 20-22 AND 26-28 DEGREES CELSIUS...RESPECTIVELY. THISCOULD SUPPORT TEMPERATURES WELL INTO THE 90S...POSSIBLY AS HIGH ASMID TO UPPER 90S...ESPECIALLY MONDAY AND TUESDAY. WITH THIS INMIND...I WARMED TEMPERATURES OVER GUIDANCE...INDICATING LOW TO MID90S. RECORD HIGHS FOR MONDAY AND TUESDAY ARE 97 DEGREES AT BOTHCHICAGO AND ROCKFORD.UNCERTAINTY INCREASES BY WEDNESDAY...WITH THE MODELS A BIT UNCERTAINON IF A COOL FRONT MAKES IT ACROSS NORTHERN ILLINOIS. THEREFORE...ITDID NOT MAKE ANY SIGNIFICANT CHANGES FOR WEDNESDAY.HOWEVER...TEMPERATURES COULD AGAIN JUMP ABOVE 90DEGREES...DEPENDING ON THE TIMING AND ACTUAL EXISTENCE OF THISCOLD FRONT.

May- 1 Jun- 2 Jul- 7 Aug- 0 EDIT: I'll have to go back and check sometime, but I think at this point last year I had 40-50, or something like that. What an amazing difference a year makes.
