Our trough is doing its thing by picking up Dorian & accelerating the hurricane to the northeast. It will still have impacts along the East Coast, especially in the Carolinas (still Category 2 or 3 there) with a brief skimming of a landfall or two cannot 100% be ruled out (before it is pushed rapidly back out to sea).
I will have another regarding what made yesterday such a unique, interesting & challenging weather forecasting day. From wake low to gravity waves to outflow boundaries, to HP supercell with wall cloud & funnel cloud, strong cap, smoke.....it had a lot going on!
Wind damage reports from yesterday to lastnight with likely tornado in Lake County, Illinois:
Cumulus/stratocumulus clouds increasing north to south over area now & will continue this afternoon.
Isolated sprinkle/light shower is possible (15%).
Highs today will run in the 70s.
Clouds burn off tonight, setting stage for coolest night for the viewing area overall since early June at 46-53. Some patchy, shallow fog may develop.
Thursday looks great with sunshine, few clouds & 70s, followed by Thursday morning lows in the 50s.
Shortwave & weak cold front will pivot through Friday with increasing clouds & potential of a few isolated showers/t'showers (25%). Highs will run in the 70s to the lower 80s.
As for Saturday & the Purdue-Vanderbilt football match-up at Ross-Ade, looks north north-northeast winds at 8-15 mph with highs in the 70s with a mix of clouds & some sun. This, after lows in the 50-55 range Saturday morning.
An isolated shower or two is possible in the area Saturday midday to afternoon (15-20%).
Shortwave & cold front will pivot through Sunday with some scattered showers & t'showers (35%) with lots of clouds & highs in the upper 60s to lower 70s.
I did raise Sunday morning's low from 43-48 to 47-54 as the clouds are expected to arrive sooner than first expected.
Front will move back north as a warm front Monday with lots of clouds & winds turning from the east to southeast with highs in the 70s.
A few showers & storms are possible as the front lifts northward (30%).
The warm front will be completely north of the area by late Monday night.
Tuesday looks bright, windy, very warm & humid with highs 85-89 with south-southwest winds 15-30 mph.
The overall trend is for warmer than normal & wetter than normal weather for mid-September:
End of September to early October looks cooler than normal overall.
Lows in the 30s are possible in the first two days of October with a freeze possible as far south as northwestern Illinois.
It also looks drier than normal.
Mid-October shows a return to normal to slightly-above normal temperatures overall with normal to slightly-below normal rainfall.
There is a tendency to keep the Southeast U.S. warmer & drier & us wetter in late October.
Here, we look to be on the edge of much cooler air in the Plains & much warmer air in the Southeast.
This will keep our temperatures potentially oscillating from cold to warm in a big way with rapid fluctuations, wet weather & risk of at least one severe weather event/outbreak (given the strong jet winds over the area & the storm track).
Out temperatures my average near normal, but there will be some well-below to well-above normal temperatures possible in the latter part of the month.
