It is now officially fall, but summer won't be letting go of its grip on our region anytime soon. Is it fair to say mother nature missed the memo, or does she write her own? Either way, hoodie fanatics may have to wait just a little while longer before busting out their favorite wardrobe.
The warmth will come courtesy of a strengthening upper ridge that will park itself across the southeastern US. This keeps the midwest in a favorable regime of breezy southerly flow, pumping up warmth and moisture. Temperature anomalies are forecast to be quite impressive, perhaps approaching record territory for some areas.
Its too early to say if Illinois will experience record highs, and only foolish weatherman predict records at this length out, but this is certainly the pattern that can deliver. Indeed, some model estimated highs do approach those territories, especially as September closes and October begins.
The CPC is well aware of the trend and has the eastern half of the country outlooked for well above normal temperatures.
Additionally, a deep, slow moving trough will develop out west. This could also promote an active period of storms, perhaps even severe, across the central plains. Some of this may spill into the midwest as well, but it is too early to iron out those details yet, but I would not be surprised to see the month end on a stormy note. Indeed, we are outlooked for above average precipitation as well. Not good news for areas that have already exceeded their annual rainfall.
This could be Summer's final stand, as models indicate this all ends with a sweeping cold front sometime in the Oct 4-7th, but now we're just talking fantasy range. Bottom line, summer wont be going away in the near future! These late September "heat waves" have become more common in recent years, an interesting trend I've noticed.
