Another summer weekend, another upper-level low impacting our weather.
You’ve heard this from us plenty of times, but the pattern just hasn’t changed much. We’ve got a blocking pattern in place across Greenland, with a trough of low pressure, often times a closed low, setting up shop over the Midwest. These lows slowly drift eastward, and as they move out, we get a couple of nice days before the next trough/low drops into the Midwest. As disturbances rotate around those troughs, they help to trigger showers and thunderstorms, especially during the afternoon and evening hours. At least we’re on the warm side of the troughs, with southwest flow aloft, meaning it’s warm and humid most of the time. Consider yourselves lucky, in places on the other side of the trough, like the Northern and Central Plains, not only have the last few weeks been quite wet, temperatures have been well below normal.
In terms of what we can expect around here, well, expect some showers and thunderstorms to develop each day, mainly during the afternoon hours, and they should diminish after sunset. These storms will be most widespread on Friday and again on Sunday as disturbances rotate through the region. Any storms that develop may produce heavy rainfall, which could trigger flooding, especially with the ground quite wet across much of the region. Temperatures will be mainly in the upper 70s and 80s during the day, but it will remain humid.
Thursday night: Partly to mostly cloudy, some showers and thunderstorms possible during the evening. Low 67-74.
Friday: Plenty of clouds, showers and thunderstorms likely, mainly from late morning into the afternoon. Some of the storms may produce heavy rain and gusty winds. High 78-85.
Friday night: Partly to mostly cloudy, showers taper off in the evening. Low 65-72.
Saturday: Intervals of clouds and sunshine, a few showers and storms possible in the afternoon. High 80-87.
Saturday night: Mostly cloudy, chance for a few showers. Low 67-74.
Sunday: Mostly cloudy, breezy, showers and thunderstorms likely, some may produce heavy rain. High 76-83.
Sunday night: Plenty of clouds, showers end in the evening. Low 66-73.
Monday: A mix of sun and clouds, chance for a few showers or thunderstorms in the afternoon. High 82-89.
