Long Range Outlook for the week of June 24
This morning a surface high pressure is centered over Lake Michigan and is slowly drifting east. This will bring a much-needed break from the heat and humidity for the next 24 hours. Tuesday a cold front is expected to drop southward across our area from late afternoon through early evening and bring ample moisture and instability to kick off some convective activity later in the day in our northern counties. Surface dew points will surge back into the uncomfortable range tomorrow because of the warm air advection across Indiana. This boundary is likely to shift slowly to the east-southeast into Wednesday. There will be a surge of warm air advection south of the front as the surface high shifts east with areas south not impacted by the front until the middle of the week. Overall, this pattern will make poor air quality less likely in the short term for most areas but with-it being June, any warm days with ample sun and light winds could bring higher AQI rather quickly especially toward the end of the week. A review of current fire activity indicates no major fires expected to impact Indiana over the next several days. Finally, a large portion of Indiana is abnormally dry with drought development likely.
