Weather Doldrums

Haven't been around to post for a bit, but am back to the regular routine for now. This is typically the time of the year when we have to start turning our attention toward severe weather / tornado outbreaks as winter fades away. Winter indeed is fading away, but for right now we're not seeing any notable severe weather chances on the horizon. In fact, the weather is downright boring for the most part (yes, for most people sunny and warm is not boring, but in the world of a meteorologist, there needs to be something a little more exciting).

We did get some exceptional cooling into Texas last Friday through yesterday. In fact, if you go back and look at historical records, a co-worker of mine found that for the 3 day period of March 13-15, each day from Friday to Sunday ranks in the top 5 coolest days in terms of how low the daytime high was (the highs these 3 days were 46, 48, and 54 respectively). So it was definitely an impressive event for down here.

Elsewhere, we're still locked into a la nina base state overall, and in fact, forecasts for this week are now warmer in much of the middle of the nation than what was in the forecasts back on Friday, which is no surprise since it is here where a la nina spring tends to focus its warmth. You often will get cooling opportunites closer to both coasts. The global angular momentum isn't as low as it has been though, but it remains to be seen if this is a sign of the end for this la nina state. Most long term modeling is actually favoring more of an el nino look down the road (later this year), so figuring this out will be key in figuring out what goes on this summer, and for you winter lovers, what type of winter we may see next year. But let's not get too far ahead of ourselves here.

I do still plan on typing up a quick review of this winter sometime soon, and will talk about how things turned out versus the consensus forecasts. We'll point out the good, the bad, and the ugly. Perhaps during this weather "downtime" I can also go into some of the global teleconnections and what they mean, if there is an interest there.
