The Streak is Over...
March 27, 2013 8:17 PM
After 12 straight days with temperatures below average, we finally broke through with an average high on Wednesday, at least most of us did. This was a good 2 days earlier than expected, but I doubt any of us are complaining. The main factor for the warmer than anticipated temperatures was the full sunshine and the better than normal mixing allowing the lower levels of the atmosphere to warm very efficiently. The good news for those yearning for spring like weather is that temperatures will likely stay around or above average into the first half of the weekend. Granted, things look slightly cooler Thursday thanks to anticipated cloud cover, but Friday and Saturday both look quite mild. Of course though, it will abruptly end Easter Sunday as much colder air starts to pour into the Upper Midwest once again. Check out the latest details below…
Here is a peak at the last week of temperatures from different spots across the area. Notice Wednesday didn’t break the streak for everyone.
It does look like we will have at least a couple more relatively mild days as fairly seasonable air will be sticking around. Here is the forecast for temperatures about 5000 feet into the atmosphere. Remember, these numbers give us an idea of how warm or cold the overall atmosphere is because surface warming does not affect this height. These temperatures give us a better idea of how warm the surface can get.
Unfortunately this mild air doesn’t last forever as colder air will start to push into the region Saturday night. Look at the forecast for these temperatures Monday morning.
Yikes!! Looks like another blast of winter… and the Climate Prediction Center agrees with this forecasting model. Here is their 6 to 10 day forecast showing probability of either above, normal, or below average temperatures.
The CPC has the eastern two thirds of the country with good chances to be below average next week. Enjoy the warm up!
