How have we managed to put this much spring into one week?! Today is the one dependably dry day of the next five. The weekend promises more warmth but showers make an extended stay. A clip-on umbrella would be good to have as showers are practically an anytime occurrence. I will be joining my brothers and sisters of the antihistamine cult to praise the pollen washing rains. And then there are all my fellow gardeners out there welcoming what promises to be enough rain to keep our flower power going strong.
Today (Thursday): A mild start (upper 50s) to this sun-drenched day only gets better with highs topping out in the mid-to-upper 70s. Winds from the south are at a leisurely 5-10 mph. A few puff ball clouds are likely in the afternoon but are mainly a novelty today. Confidence: High
Tonight: A gorgeous evening awaits us with readings around 70 and calm winds. Readings will eventually slip back to upper 50s before dawn (to near 50 in the cooler suburbs). Clouds begin infiltrating the area by late night.

Tomorrow (Friday): Thundershowers up in the Great Lakes could come into play today and it could be just about anytime, but most likely in the afternoon. The problem is the upper air winds are coming from the north and could latch on to a few of the storms in western Pennsylvania and bring them on down (40% chance), especially in our western suburbs. They probably won’t be more than a few light showers by the time they get here. The bulk of the day will be rain free but plenty cloudy. Temperatures are still likely to reach the lower 70s by afternoon. Confidence: Medium
Tomorrow night: Showers are still possible (20%) but most of us should have a dry evening. Clouds are abundant through the night. Lows should only slip to the upper 50s to lower 60s. Confidence: Medium-HighA LOOK AHEAD
Saturday is just dandy in the temperature department with readings slinking up from the 60s into the lower 70s. However, lots of clouds are a given and showers are likely to become an increasingly common feature as the day progresses. Breezes will be picking up from the south and humidity becomes noticeable, helping to feed the shower potential. The chance of rains today rockets up to 70%. The same is true for the evening. Lows should only fall to the low-to-mid 60s. Confidence: Medium
Sunday promises plenty of scattered showers (70% chance) and maybe even a rumble of thunder as warmer air destabilizes the atmosphere. Rain chances reach their maximum in the afternoon. Despite the showers, we have our share of dry moments (best chance in the morning) with highs should still very comfortable mainly in the mid-70s. Overnight lows only fall to the low-to-mid 60s. Confidence: Medium
Monday is likely to actually start out with clearing skies as the surface low heads up to New England. However, the upper level low approaches from the west and clouds return by afternoon with showers possible by evening (40% chance). Spring time temperatures hold tough with highs reaching the low-to-mid 70s. Confidence: Low-Medium
