It's starting to get hot in here


It's not summer yet, but we're getting there. Temperature are expected to raise to 86 degress today. I nice and hot one. Well maybe warm. 90 to me officially makes it hot. However, dew points are modest to low, around the mid 50s, so not a lot of humidity to worry about.

I'm sure the next day or two will see and increase in humidity as the next front (and thunderstoms) approach the region. Tomorrow's high's aren't expected to reach into the 80s, but late day thunderstorms may still be a possiblity.

The last system that passed did so during the overnight hours and had already lost the daytime heating, which meant little convection to enhance the system. The incoming system, as the forecast graphic shows, will have lots of moisture with it, so event if there isn't a lot of strong thunderstorms, we could be looking at flooding conditions.

Andrea formed, and unpredictable

Well as the post was being published last time, The National Hurricane Center (NHC) did if fact name the subtropical system. The first named storm for the season, which is looking to be another active season.

Originally it was thought the system would move toward the Florida coast, and make landfall, and fall apart. As of this hour, the system center is still off the coast and now looks to meander off toward the east. However, no more advisories will be coming from the NHC on Andrea, since organization is poor, and there is a severe lack of convection in the system.

Locally, we are looking at some possible thunderstorms overnight. If we see any, they'll be small and weak. Nothing to be excited about.

Is it a tropical storm or what??



This is quite an interesting feature, looking very tropical in naturel. However, it if anything is subtropical.

The core is likely a cold core, which is completely different from tropical systems that are warm core. If you've ever been in a hurricane near the center, it's quite an intersting feeling when the rain and wind are coming down so fast, and it's completely white out conditions, and yet your hot as hell. The rain from a hurricane is warm like taking a shower at home.

The hurricane center is sending an investigating plane into the system sometime today. Depending on it's findings, we could possibly have a named system, although not likely. This would not be the first time a system was named before the June 1st official start to the hurricane season. Like 2004 when we had a very, very early April storm form in the Atlantic.

Locally, it looks like the rain will be held off until Thursday, much later than I originally thought. Seems the system out west it take quite a while to reach the eastern shores.

Active pattern out west, quite near home

While High Pressure is in control today around the DC area, bringing us semi-warm temperatures and clear skies, the last few days out in the the Central Plains has been active chase weather.

A possible (most likely) F5 tornado touched down in Greensburg, KS this past weekend. May 4th and 5th saw multiple tornadoes with some being strong F-3 or higher.

Locally, we have been working with High pressure and although out temperatures have been holding to the 60s upto near 70, we've had mostly clear skies. Monday, and Tuesday look to follow this trend. However, the system that brought much of the storms out west will arrive in this area sometime in the short future (Tuesday late evening or Wednesday). It will be significally reduced in intensity when it arrives past the Appalachains.
