A stalled frontal boundary continues to hang across Minnesota and extends south all the way to Texas. Weak ripples of energy working along this front brought periods of showers and t-storms across the region from Sunday morning through Sunday night... then again this afternoon. Another ripple will produce a chance of more showers and t-storms across Iowa. some of these showers and t-storms could move into the area overnight tonight. As a result, I've increased our chance of showers and t-storms a bit for the overnight hours tonight. It is still a bit unclear how this will play out, so keep an umbrella handy if you plan to be out late tonight. The sevre threat for tonight is rather low. some o fths torng storms could be rather gusty and produce a lot of lightning and heavy downpours, but organized severe weather is not expected. It will be a very mild night. look for overnight lows in the upper 50s to lower 60s.
Another ripple of energy will work along that stalled front tomorrow. This chunk a energy has a bit more moisture to work with and will be a bit stronger. As a result, look for another round of showers and t-storms to roll into the area sometime during the early to mid morning hours. Once the rain gets here, it will more than likely through the afternoon into the first part of the evening. Again... the threat for severe weather looks rather low at this point. Abundant cloud cover will keep instability low... and with only light to moderate wind shear present, it will be really hard for storms to get organized. Clouds and rain will keep temperatures in the lower to middle 70s tomorrow. The good news is once this last disturbance exits the region tomorrow night, the front should get kicked east. This will turn the rain of for a couple of days.
Looking Ahead... It will be dry and warmer Wednesday and Thursday with highs in the low 80s.
Another system will bring a chance of showers and t-storms late Thursday night into Friday. The clouds and rain chances will knock highs back into the 70s Friday.
Next weekend will be cooler with highs in the upper 60s to around 70º. The latest forecast data has me keeping at least a slight chance of rain in for both days, although the better chances Saturday will be across the southern third of the viewing area.
Just isolated storms are possible to start the following week, with high temps warming back into the mid 70s Monday to near 80º Tuesday.
Have a great night and keep those umbrellas handy for at least another 24 hours! -Cory Malles
