Hoosier Posted February 20, 2017 Author Share Posted February 20, 2017 Gil Sebenste is all in on Wednesday. He's thinking 80 in the Quad Cities, which would be stunning when considering the all time February high. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted February 20, 2017 Share Posted February 20, 2017 The rain held off til after noon, but clouds kept the temp rise slow. We maxed at 60 and have since fallen back to 59. Link to comment Share on other sites More sharing options...

Clouds have really thickened in the last half hour, but the temp is still ever so slightly climbing, tenth by tenth. So far we've gone 70/65/69/68 for Fri-today for here, while MLI has gone 73/70/74/~70. Link to comment Share on other sites More sharing options...

I would be all in as well, but the rains from today/tonight may dampen up the top soil just enough to take a slight bit out of the extreme temp ascensions we've experienced the past several days. I'm gonna go with 74 for now, for MLI based on that. I'm thinking the past few days would have been a few degrees cooler had we had a recent rain. I guess we'll see. Going to be interesting. EDIT: I had to laugh when I read back what I just wrote. 74 a relatively conservative forecast in Feb. That's just wow. EDIT2: It's now Link to comment Share on other sites More sharing options...

Chambana Posted February 20, 2017 Share Posted February 20, 2017 I'm going to be extremely irritated if we don't rise another degree today, this could possibly be the 3rd day of this warm stretch we have just tied records. Lol. Link to comment Share on other sites More sharing options...
Hoosier Posted February 20, 2017 Author Share Posted February 20, 2017 Chicago will have at least 3 days of 70+ out of this stretch. If it ends up at 3, that would be the same number as what occurred in all Februaries prior to 2017. I did some comparison with the 80 degree days in March. Prior to 2012, Chicago had 10 days of 80+ in March. March 2012 added 8 days of 80+. Link to comment Share on other sites More sharing options...
cyclone77 Posted February 20, 2017 Share Posted February 20, 2017 Looks like the 5-min obs might be slightly overdoing the temps. The METAR shows 20.6C, which equates to 69.08F. The 5-min ob site looks like they round the C temp down to two sig digits first, and then converts to F. So 20.6 rounds up to 21, which then equates to 69.8F. The true temp in F is actually 69 (69.08F). EDIT: Of course during the course of some of the reported 70F obs, the temp in C may have bumped a bit higher than 20.6. No way to know though unless they have an option to switch it to C. EDIT2: The list of raw obs does show the temp in C, but unfortunately they're all rounded down to 2 sig digits as well lol.

Yesterday came in at 69 officially and today the 5 minute obs have been rounding to 70 but the last 2 official hourly obs have shown 69. So if the next hourly ob doesn't show 70 we'll have to wait until the 4:30pm CLI to see if there was an intra hour 70. Today will determine of we bag 2 or 3 70+ in this stretch with Wednesday looking like a lock. Link to comment Share on other sites More sharing options...

Yesterday it was just a low deck, today it's some of the densest fog I've seen in quite a while. Still less than a .25 mile visibility at 11am. Fog and clouds cleared out much quicker today compared to yesterday, despite a stronger inversion. Warmed up to 64F. Link to comment Share on other sites More sharing options...
Chambana Posted February 20, 2017 Share Posted February 20, 2017 Record officially broken at CMI with a reading of 72 during the hourly obs. Impressive warmth. My step fathers personal weather station is saying 73. Tuesday and Wednesday have potential to break records from 1922 and 1930 respectively.

cyclone77 Posted February 20, 2017 Share Posted February 20, 2017 DVN also has some concern regarding added soil moisture, and how it may slightly impact temps Tue/Wed. I'll be curious to see how much, if any impact it has. If mixing reaches up to 850 mb, where temperatures are progged from 10 C to as high as 14 C, then mid to upper 70s would be widespread. The one change compared to the past several days will be the added soil moisture from the on-going rainfall, which could buffer these extreme temperatures some. Thus, for now will maintain highs from the upper 60s north to mid 70s south, which would be in the range of 5 to 10 degrees above records for the 22nd and possibly pushing all time February highs at the climate sites, as listed in the climate section.

Depends on winds and ambient dews, but I would imagine it will have at least a couple degree effect. Easy to undershoot lapse rates this time of the year because of a near total lack of evapotranspiration. Link to comment Share on other sites More sharing options...
csnavywx Posted February 20, 2017 Share Posted February 20, 2017 Febumay continues. Just missed hitting 80 degree mark. Got to 79 right before a mid-deck spoiled the party, which is still a record. Looking to be a very warm night with the clouds around. Link to comment Share on other sites More sharing options...

Rain looks to be on a weakening trend as it gets this far east, but the trade-off is that we didn't enter this stretch as dry as you guys. Link to comment Share on other sites More sharing options...
donsutherland1 Posted February 21, 2017 Share Posted February 21, 2017 Chicago's historic February warm spell: High Temperatures: February 17 67° (old record: 60°, 1880) February 18 70° (old record: 62°, 1981) February 19 69° (old record: 65°, 1930) February 20 70° (old record: 64°, 1930) Link to comment Share on other sites More sharing options...
cyclone77 Posted February 21, 2017 Share Posted February 21, 2017 This is shaping up to be one of the more impressive weather events I can remember around here. Tagging 70 in Feb is a huge feat in it's own, but to do it 4 days in a row, with a potential for 6 days in a row? Just insane. Wednesday looks like a slam dunk 70+. Point is now up to 75, so a new all-time record may be set again. Tomorrow is somewhat questionable though, as we will have wet soils from tonight's rain, and will have to contend with weak caa much of the day. Point has 68, so it will be close. HRRRx only has it making 66-67. Even if tomorrow fails to reach 70, having 5 out of 6 days in a row AOA 70 this early is just madness. Something we will definitely never see again. I'd bet my 401K on it lol. Here's a nice graphic put out by DVN with some other sites in the cwa as well... Link to comment Share on other sites More sharing options...
Snowstorms Posted February 21, 2017 Share Posted February 21, 2017 Only hit 40F today at YYZ which is nothing compared to you guys. Warmest day of this thaw (so far) was 53.4F the other day and 52.7F yesterday. We could make a run for 55-59F on Wednesday. Link to comment Share on other sites More sharing options...
Hoosier Posted February 21, 2017 Author Share Posted February 21, 2017 MLI put up a +32 departure today (+36 on the high and +28 on the low). They had never put up a daily of +30 or greater in February (have had +28-29 several times). The +32 also exceeds their highest daily departure from March 2012.

Hoosier Posted February 21, 2017 Author Share Posted February 21, 2017 3 or more consecutive days with record highs in Chicago, since 2000: March 14-22, 2012 (9 days) February 17-20, 2017 (4 days and counting) July 4-6, 2012 (3 days) March 6-8, 2000 (3 days) If everything goes right, the current streak could extend to 6 days.

cyclone77 Posted February 21, 2017 Share Posted February 21, 2017 Picked up 0.14" overnight. There's actually some sprouts of new green grass this morning. Last few HRRR runs have MLI languishing around 64 this afternoon. Point has 70, so we'll see. The rains overnight were less than anticipated, so hopefully that should help. MLI/DVN picked up 0.21"/0.35" respectively. Link to comment Share on other sites More sharing options...

Hoosier Posted February 21, 2017 Author Share Posted February 21, 2017 Low at ORD was 54. If that can hold the rest of the day, it would tie the all-time record high min for February. In any case, looks like a good chance it stays warm enough to beat the daily record high min. Link to comment Share on other sites More sharing options...
