After a nagging drought it's good to be getting rain again - have you noticed how green it is out there? Better than yellow, or mud-brown, which is what much of Texas is waking up to as flood waters begin to recede. Today's blog includes a few stories about a possible climate connection, and El Nino may be a factor as well, helping to energize the southern branch of the jet stream. Enjoy 80s today; a surge of Canadian air cools us off over the weekend but long-range guidance is hinting at real heat within 2-3 weeks. We're probably due.
Never a dull moment in the weather department, and with a moderate drought it's hard to get too indignant about a soaking rain, especially on a Tuesday. The drought is fizzling as tropical moisture finally reaches Minnesota, a trend which should spill over into much of June. After a raw day yesterday you'll get a chance to whine about the heat and humidity today and tomorrow as the mercury surges past 80F and dew points push into the 60s. Instant summer.
Well, the sun did come out by late afternoon and evening, allowing us to salvage a little of our Memorial Day, especially central and southern Minnesota. Up North it was a total wash-out, but then again the weather Up North was pretty fine Friday and Saturday. We dry out today, a few 80s by Wednesday and Thursday before we dry out and cool down for the weekend. It could be worse - you could be looking for higher ground in Austin, Texas.
Look at the bright side: you won't have to worry about a painful sunburn today - and watering will be optional until further notice. The big news, of course, is that the drought continues to ease as we limp into a much wetter pattern, one that shows no sign of quitting into early June. Details on Memorial Day weather, and why we won't be getting another boat anytime soon, in today's weather blog.
NOAA's NAM model prints out 2.49" rain between now and late Monday night. Naturally. Major holidays attract storms and this Memorial Day should be no exception. I hope you had a chance to spend some time outside yesterday. The weather was so-so in the metro but gorgeous up north. Today and tomorrow: not so much. That said (while gritting my teeth) we do need the rain.
