Thank you for stopping by the Weather Watch 12 blog! The weather buzz over the past several days has been on the big weekend warm-up. For anyone that follows this blog, you know the April 7-11 timeframe was a date range we highlighted in FEBRUARY as to when the first 70s of the season may be possible!
The warm-up is still on target. However, the models are still shifting around the position of low pressure, and also the timing of thunderstorms. Those details as the weekend nears will be handled with the latest data on WISN 12 News.
For the big picture, let’s look at what should be the warmest day this weekend. The 12Z GFS is forecasting temperatures in the 60s at 7am Sunday! Just click below to see the forecast temperatures.
Along with the warm air, moisture will be on the increase. The highest dew points so far this season will surge into southern Wisconsin. At this early point many models are forecasting dew points in the 60s…including the GFS.
Below is the 12Z GFS dew point forecast map valid at 7am Sunday. It may feel ‘sticky’, or ‘humid’.
With warm, moist air in place, both a warm front lifting north, and a cold front pushing in will trigger showers and t-storms this weekend. The Storm Prediction Center’s convective outlook is highlighting our area as a spot that could see severe weather this weekend.
