Record-Setting May Temperature Swings, Weekend Severe Threat
Look at those highs forecasted for today! Amazing, eh? With the cold weather, and the fact that the Midwest saw snow as recently as last week, it’s quite remarkable to be talking about 90s for highs.
Welcome to 2013’s weather patterns: extremes. It gets better if you contrast yesterday’s low temperatures with what we are looking for this afternoon. We’re seeing the potential for some of the largest temperature swings over a 2-day period in May history, at least for a few select locales.
Let’s take a look back in time, back yesterday morning… remember these temperatures?
Those Rs next to the numbers indicate record lows. Detroit and Green Bay both achieving that unwanted goal.
Remember that map at the top of this page, now?
Well, contrast that top map with the map above of the lows from yesterday, and you get the following map:
I would imagine your eyes immediately slide toward Minneapolis/St. Paul and Chicago, as well as International Falls, MN. Those are all places seeing a 50+ degree rise in temperatures from Monday’s lows to today’s forecasted highs. Pretty impressive.
Some of these should rival records. St. Louis and Minneapolis, for example.
Look at St. Louis’ largest May temperature swing:
Theirs took place in 1976. The one for Minneapolis is a little harder to reach (although the forecasted change is close), but quite a bit older of a record as well.
Maybe you want a cooldown, or maybe you are worried about/looking forward to storms (funny how opinions tend to be such polar opposites on stormy weather). Well… we’ve got some of those on the way for you as well.
A low pressure center is looking to rise northward for Saturday and Sunday, drawing up some warmth and humidity into the Midwest.
I may be suiting up with the old chase gear this weekend, should this develop into a more mature severe weather scenario.
Sunday looks interesting as well.
We’ll be watching all of this closely. For now the storm’s tracks are VERY variable… so don’t plan anything based on these maps just yet.
