Behind the Low

After yesterdays' extensive rainfall and severe weather that crossed through the state, the low pressure system is currently slowly moving over the state. The low became a cut-off low pressure system yesterday, indicating that it would likely move slowly as well as weaken. That is what current surface trends are indicating, as the lowest pressure has rose from 987 mb to 990 mb over the past 5 hours. The system will still have some showers and snow showers wrapped around the circulation that is likely to effect most of the state through this afternoon. Extreme northwest Iowa is still under a Winter Weather Advisory for snowfall accumulations in the 1-3 inch range. The heaviest snowfall has luckily stayed off into South Dakota and Minnesota.

Temperatures today will struggle, with a majority of the state actually seeing falling temperatures through the afternoon. Expect highs in the 30s and 40s for most of the state, likely to occur before Noon. Some snowfall may stick around through the night and last into tomorrow, with mainly flurries. Expect chilly temperatures through Saturday before we begin to warm up nicely for next week.

On the note of severe weather that occurred last night, the National Weather Service offices are conducting surveys throughout the day today. Once those are posted tonight I will try to also update the blog with all of the surveys and any other information about the severe weather on April 10.
