Sorry my little hiatus the past couple days, I was up north at my cabin again and didn't have any internet access. Hope you all had a great weekend whether you were visiting family for Easter or not. Let's get right down to business though. I am sure most of you have noticed how strong winds have been today, but what is causing them?
Yeah the map is busy, but it does a great job at depicting cloud cover, wind speed, wind direction, fronts, and pressure systems all at once. What I would like you to take from this surface map is the high pressure system centered over Montana and the low pressure system in southern Michigan. Looking at our current barometric pressure reading of 1030.07 g/kg it is pretty evident that we are under the affect of the high pressure system. Well then why is there overcast skies, you may be wondering? We are in fact right in the middle of these two pressure systems converging, which explains the cloud cover. The mixing of these two pressure systems is also what is causing the gusting winds.
Cooler temperatures than we experienced in March seem to remain the trend in April thus far. As you can see the jet stream is very defined and relatively horizontal in orientation over the northern U.S., causing high speeds.
While we have had an unusually warm spring in Wisconsin so far, it is only early April and we are by no means in the clear in regards to cold-snap risk. Therefore I will continue to keep a close eye on frost risk for you all.
As you can see projections for temperatures below 32 degrees F and frost risk don't bode well for the Northern U.S. It is rather interesting how similar the jet stream for today and at risk areas for tomorrow morning look.
