FORECAST DISCUSSION:
Michigan started off May in a picturesque way with temperatures well into the 60s and 70s throughout the state and ample sunshine coupled with the warm air. Rain showers hung around the state, but the majority of showers occurred in the overnight hours and did not hinder daily activities. We start off this work week the same way as the weekend ended—warm and mostly sunny. Today’s weather will give way to a Low-pressure system and associated rain showers tomorrow, Tuesday, afternoon with a chance of organized storms for Tuesday afternoon and evening hours for southern Michigan. On Wednesday, we look to bounce back with relatively dry conditions in the southern portions of the state with the upper peninsula having some left-over showers from the exiting pressure system. Thursday presents us with yet another pressure-system along with providing us additional rain showers for much of the state and a slight cool down for Thursday and Friday. The Low-pressure system on Thursday will shift winds for Thursday and Friday towards the northerly direction, which is the reasoning for the cooler temperatures for parts of the state. We end the work week with dry conditions and temperatures hanging around the 60s for much of the state.
For air quality, low end Moderate conditions can be expected throughout the week due to shifting wind directions and multiple frontal boundaries crossing the state. For Ozone, surface temperatures are not expected to be warm enough for Ozone development, along with an unfavorable wind direction throughout the week. Changes in airmass due to the aforementioned frontal boundaries will keep not only Ozone at bay, but PM-2.5 concentrations at bay as well. Stagnation does not seem to be a threat this week due to the wind shifts and cleaning out of airmasses early-to-mid week.
EXTENDED FORECAST:
The weekend looks to be on the wetter side of the forecast, with spotty rain showers Saturday and decreasing rain chances on Sunday. This will keep overall air quality near the Good range.
