Sunny & warm day ahead, but cooler weather is right around the corner

  • 0

ROCKFORD (WREX) — Summer's last hurrah may be Sunday, as high temperatures soar into the 80s. Cooler and more typical temperatures return by midweek.

Near 90° Sunday, but cooler weather is near:

High temperatures Saturday climbed into the middle 80s, but Sunday could feature even warmer weather. Clear skies overnight Saturday result in a pleasantly cool start to the day Sunday, with many locations falling to near 60°. Under clear skies and generally light wind, some patchy fog cannot entirely be ruled out. Dense fog does not look likely, as winds should pick up after sunrise Sunday.

As the sun climbs above the horizon, temperatures begin their upward journey. By midday Sunday, temperatures will be in the middle 80s. Before the day is done, high temperatures to end yet another gorgeous weekend in the Stateline approach 90°.


Near average temperatures look likely through early October.

Mother Nature has been slow to give us cool weather of late, but she promises more typical conditions by midweek. High temperatures Wednesday may not make it out of the 60s. This is right on time, as astronomical fall begins Wednesday.


Lows overnight Wednesday into Thursday morning drop into the lower 40s.

Let's talk lows! Temperatures Wednesday night fall into the 40s. It isn't entirely out of the realm of possibilities that a few very localized areas could briefly drop into the upper 30s. Don't worry about frost. If any location does make it into the 30s, it likely won't be low enough or long lasting enough to cause any damage to crops.

Before getting to fall, rain chances return:

Rain chances gradually increase overnight Sunday into Monday morning. Expect spotty showers to dot the radar as you send the kids out to the bus stop, so make sure they have rain gear handy. Monday does not look like a washout, but be prepared for hit-or-miss showers through much of Monday morning and afternoon.


The window for widespread rain and storms extends from late Monday into early Tuesday.

Better chances for rain and thunderstorms move in overnight Monday into Tuesday. A potent cold front brings the best chance for widespread and heavy bouts of rainfall. Current forecast thinking keeps severe threat to a minimum, but of course keep a close eye on this in the days to come. A better idea of potential impacts should come about by Sunday and Monday.
