"Cristobal" brings heavy rain today
We're dealing with widespread rainfall today as the spectre of heavy rain looms in our area thanks to the arrival of the storm system that was once Tropical Storm Cristobal. That system continues to march northward, moving up the Mississippi Valley, eventually taking aim on northern Wisconsin and Ontario, Canada. Heavy rainfall is expected to develop in the early to mid-afternoon with up to an inch of rainfall by the evening commute. Even heavier rainfall is possible in the early evening. While severe weather isn't necessarily expected, a few storms could potentially produce tornadoes as there is going to be a lot of wind shear associated with the storm system. Otherwise, heavy rainfall is the primary concern this afternoon and evening and a Flash Flood Watch will be in effect until 7:00 AM Wednesday. Rainfall totals of two to four inches will be possible across the area, potentially leading to urban flooding, mudslides, and washouts of roads and highways.
Temperatures will continue to slowly drop off and then remain steady in the 70s as rain spreads across the area.
Windy and damp Wednesday
Winds will become stronger later this evening as the remnants of Cristobal pull away to the northeast and showers will taper off by midnight. Look for overnight lows in the upper 50s with northwest winds occasionally reaching 30 miles per hour. We'll have periods of light rain developing in the morning, lingering through the early to mid-afternoon Wednesday with high temperatures in the upper 60s. This shower activity will be the product of a weaker storm system that will move in from the west. Things will feel even cooler than the upper 60s tomorrow as northwest winds will gust to 35 miles per hour at times.
Isolated showers Thursday
A disturbance riding behind the departing storm system will bring a chance for a few isolated afternoon showers and thunderstorms Thursday. Otherwise, we'll have sunshine throughout most of the day with high temperatures in the upper 70s and a gusty west breeze.
Mild sunshine this weekend
Friday looks bright and pleasant as high pressure from the Plains drifts into the region. Expect sunshine, lighter winds, and high temperatures in the lower 70s to round out the workweek.
The weekend forecast is looking sunny and tranquil with mild temperatures and low humidity levels in our weather picture. High temperatures will be at or slightly below the seasonal standards with low to mid-70s expected.
