HOWLING WINDS
Gusts in our area have been in the 35 to 50+ mph range for several hours now. The parent storm that brought us the thunderstorms this morning is now pushing into MO. Central pressure with this intense mid-latitude cyclone has been as low as 988mb, and quite possibly lower. Central pressure in a minimal Category 1 Hurricane is about 980mb; two entirely different storms but, intensity wise, not to0 far apart. As the Low pushes off to the east north east our winds will slowly subside though it will be a very windy night.
Severe weather was isolated this morning even though we were under a tornado watch. The atmosphere probably just didn’t have enough juice / moisture to sustain long lived supercells through our area. The amount of wind shear was off the charts, though general consensus here in the 40/29 weather center was that the amount of wind at mid levels may have in effect cut off inflow of warm moisture laden air to developing storms. Sunshine and heating was absent too; though, later in the day the right combination of ingredients did come together for a series of potent thunderstorms east of Little Rock. Our thoughts and prayers go out to all who were affected by the Dumas tornado as well the several others that hit today close to the AR / MS border.
We’re watching developments closely for what looks to be round two of 2007, thunderstorm-wise. A trough with a lot of energy upstream is digging just of the British Columbia coast. Once again, this will likely develop a surface low to the west of us by the mid week time frame. As mentioned in other discussions recently, position and specific timing will determine the severity of the associated weather.
Kite flying anyone?
