This x2. Tue-Thur is the biggest question as to where the hottest temps are located and where the ROF pattern sets up, with the first initial push of ridging. Past history says bank on the southern end of guidance for that. On the flip side, the amount of support for the ridging and widespread hot temps to build into much of the region for Fri-following week is tremendous. .
Or not... In 2020 fashion, the lake enhanced OFB came to a halt right along the border. A lake breeze has developed in NE IL, but is in no rush to move inland. 90+ is easily in the bag, and will probably make a run towards 93/94 or so. .
Lake enhanced OFB quickly moving south along the WI shore, and just about at the IL/WI border. That might be enough to prevent 90+ today, as it’ll easily be through ORD before noon. 83 at ORD as of now, so the race is on. .
Agree. Would like to stay on the drier side overall, in addition to guidance holding firm or even looking better (ridge further north to keep ROF north). Problem re precip... All guidance outside of the Euro/UKMET have widespread t’storms and heavy rainfall tomorrow, and then some on Saturday as well. .
Finally 90+, and up to 91 at ORD. This lingering cloud deck has been eroding a bit, just in time before anvils move into from the t’storms across the SW metro. .
90+ at ORD will likely be delayed and a closer call than it should have otherwise been for today. Cloud deck associated with an MCV continues to sit in place and regenerate across portions of the metro, slowing the temp rise this morning. .
