Cool, Damp Days Ahead

***Watch WISN 12 News for the latest weather information!***

Thank you for stopping by the Weather Watch 12 blog!  Hopefully you had a chance to enjoy a beautiful Wednesday with some sunshine and highs well into the 60s.

Cooler and wetter weather conditions are in the forecast starting Thursday and likely lasting through the weekend.  A storm system moving into the Midwest will first turn the winds off Lake Michigan on Thursday, keeping temperatures cool – in the 40s and 50s.

Rain chances will be low on Thursday, but rain showers are likely beginning Friday afternoon.  The storm system that will deliver the changes will be a slow mover, which explains why clouds, showers, and cool temperatures will be the rule the next several days.

Below is the forecast surface map from the HPC for Saturday morning.  That is when the center of low pressure will be near southeast Wisconsin. 

Surface Map Saturday, April 16   

Unlike the storm system this past weekend that saw the surface low stay northwest of Milwakuee bringing in warmer weather, this area of low pressure will slide south of our area.  With this low position, the warm air stays south, but so will chances for severe weather.  

High temperatures Thursday through Sunday look to be well below average in the Milwaukee area.  The chilly weather will be here in full force, along with breezy weather on Friday.  Check out the forecast highs to end the work week.  The NAM computer model forecast below shows readings between 40-45 on Friday at 7pm. 

NAM Temperatures Friday April 15  

With the forecast track of the low, it appears that precipitation in southeast Wisconsin will stay in the form of rain.  At this point temperatures aloft and at the surface don’t look quite cold enough to support snow in this part of the state.  If the low track changes and shifts farther south, then some wet snow would be possible.

The storm does appear fairly wet, so if you are looking for a good time to apply lawn fertilizer I would try to get that done by noon Friday.  From Thursday through Saturday a half inch to one inch of rain is forecast by the NAM computer model.  Just click below.

Overall the next 7 days look to bring above average precipitation to the area, along with below average temperatures.  Make sure to watch WISN 12 News for the updated timing of rain.

Please post any questions or thoughts to the comments section of the blog.

Have a great day!

    • Steve,

      Outside of a day or two here and there the rest of the month looks pretty active with numerous rain chances. We are now repeating January which gave us numerous precipitation chances. Overall I see the active weather continuing through about May 9-13 when the next signature storm arrives.

      In about a week or two I will issue the forecast for the next few months.

      Jeremy
