Summer Weather on the Way for Many!
The warm sector (to the east of the
cold front and to the south of the
warm front) will see highs in the 70s and 80s area wide. This will likely be the first 80 for many in the Midwest. With dew points on the rise and ample surface heating, the atmosphere will become prime for severe weather, with CAPE values approaching 3000 J/KG from Wisconsin on south. A severe weather outbreak is certainly possible on Thursday in the warm sector and ahead of the cold front. We will have to see just where and when this system sets up. The 00z GFS (below) is firing up some thunderstorms for Thursday evening along the cold front. While the front will not bring much in the way of colder air, it will create necessary lift and convergence to develop strong to severe thunderstorms with heavy rains. Back to the temperatures, the chart above is forecasted high temperatures for late next week off the 00z GFS model run. Another temperature map is attached below coming off the European weather model, showing a major range of temperature across the Midwest. The barrier between warm and cool with depend solely on the track of the system mentioned above, either way warmer weather and a kick start to severe weather is on the way for the first full week of May.
