Severe Weather Possible Sunday and Monday
At least one tornado has been reported in the United States every day since May 3rd. That is a week straight of tornadoes. Most of the severe weather for the past week has been concentrated in the Southern Plains: Texas, Oklahoma, Kansas, etc. Once again today, severe weather and tornadoes are being experienced in those same areas with another strong storm system. That same storm system will begin a move towards Wisconsin starting Sunday.
This strong area of low pressure will stall a warm front just south of Wisconsin Sunday evening. This means that no big warm-up will be expected for the Milwaukee area on Sunday - that arrives in a weak fashion in Monday. After a few morning light rain showers the majority of Sunday in Milwaukee will stay cool under mostly cloudy skies. By Sunday night the cold front associated with this low pressure will begin to move eastward across Wisconsin and bring storms with it. Due to the sincere strength of this low pressure, there is a low chance that some of these storms could be strong to severe as depicted by the severe weather outlook by the National Weather Service seen below. If you are confused by the new way the NWS outlooks severe weather read this previous First Alert blog post.
The outlook shows that the risk for severe storms is greater just to our south and west where they will see warmer temperatures and more clearing. If southern Wisconsin sees more sunshine and temperatures warming past 60°, our risk for severe weather may increase.
If any strong to severe storms do develop the main threats will be large hail and damaging wind along with heavy rain. The threat for a tornado is very low and isolated.
The timing for these storms will start around 9 PM Sunday night and last through Monday early afternoon. Since severe weather will be possible all throughout this time period, there is also a chance for severe weather on Monday with the same threats.
Bottom line is this - even though the chance for severe weather is marginal at best it is always wise to know the threats and conditions and be prepared. Keeping the weather radio on and cell phone volume up Sunday night would be a good idea. As always, the First Alert weather team will keep you up to date with any forecast changes, look for those here. And the CBS 58 First Alert Weather App is always a great resource to get warnings and track the radar.
