FORECAST IN DETAIL


The dry air is on its way today but really takes until late in the day to convince us that it is here to stay. Tomorrow has nice day written all over it with a warm sun and low humidity. A mega-cold front coming out of the Midwest may hold off long enough to salvage most of Saturday. But Sunday looks like a bust with highs lucky to make 60 and possible showers.

Today (Thursday): A few showers should skip through the darkness but with a little luck they will be gone by mid-morning (40% chance of showers that is). There also may be areas of fog early. The drier air piling into the area should start to break up clouds noticeably by mid-afternoon. That gives us the opportunity to make the upper 70s to lower 80s for highs. Confidence: Medium

Tonight: The skies continue to shed most clouds by evening with readings in the 70s to enjoy. Only a very light breeze keeps it comfortable even as lows slip to the upper 50s to lower 60s. Confidence: Medium-High

Tomorrow (Friday): This is the day we were waiting for with abundant sun and low humidity. Highs should easily make it to the lower 80s and breezes remain light. Confidence: High

Tomorrow night: Another great evening to get out and about with readings in the 70s. Lows are manageable in the mid-50s suburbs to lower 60s downtown. Confidence: High

A LOOK AHEAD

Saturday poses a greater forecast test as a strong but slow-moving cold front approaches from the Midwest. There is a fighting chance that it could hold off and highs reach the upper 70s to lower 80s. But if it picks up the pace, afternoon clouds and possible showers (20% chance) could keep up us in the mid-70s. Word to the wise: if you are heading to the pumpkin patch, earlier is better. Overnight the northwest winds increase and showers become more likely (40% chance). Temperatures march downward ending up in the upper 40s to lower 50s. Confidence: Medium

Sunday is just not what we had hoped for and will be a clear wake up call that summer is no longer with us. Clouds are thick and showers are likely (70% chance). What really gets your attention is those temperatures that barely budge. Highs in the upper 50s to near 60 would be the first time for that since late April. Showers may linger into the evening (40% chance). Clouds stay put which helps keep lows in the 40s but far western suburbs might clear soon enough to reach the upper 30s. Confidence: Medium

Columbus Day (Monday) looks great with plenty of sun but the cold air mass is firmly in place. This keeps highs no better than low-to-mid 60s.So for those of you lucky enough to have the day off, jackets are a good idea. Confidence: Medium-High
