Remarkable Longivitey-Hornet Nest at UWGB

I recently noticed this bald-faced hornet (Dolichovespula maculata) nest hanging in a tree on campus. Judging from its size it was obviously built last summer and abandoned in the fall. What is unusual about this is that it is in only slightly worse condition than the ones I found in Stoughton in late December, despite being exposed to the elements for a much longer period of time. It is not as if we have had particularily benign winter weather here in Green Bay either, with numerous snow, rain and wind storms.

Notice the new leaves forming on the tree. It's only a matter of time before the nest is hidden from view-for the second time!

Weather Event #12-El Reno & Randlett, Oklahoma tornadoes

Three tornadoes developed in Oklahoma on Monday, April 24, 2006. All three were rated F1 although the one that did the most damage was in actuality probably the weakest of the three. This was the anticyclonic tornado that hit the El Reno airport, unroofing a hanger and shifting at least one plane on its tarmac.

The airport tornado had been preceded by a more classic, mesocyclonic tornado that was quite large and judging from the video and pictures I have seen it was probably capable of at least F2 damage. It threatened the west side of El Reno but encountered only trees and was rated a "low F1", while the anticylonic tornado that probably had lower wind speeds was a "high F1"!

The third tornado came from a different storm, in far southern Oklahoma near the Red River. It also damaged only trees (F1 rating) but was a well-developed tornado that would have been highly dangerous to anyone in its path.

Weather Event #11-Severe Weather and Tornadoes Continue Over Easter Weekend

Weather Event #10-More Signs of Spring

An outbreak of severe thunderstorms developed rather unexpectedly over Iowa, Wisconsin and Illinois on the evening of Thursday, April 13. Several strong, destructive tornadoes touched down across eastern Iowa with at least one fatality confirmed. In southern Wisconsin, widespread hail larger than golfballs caused considerable damage.

A series of thunderstorms passed over Green Bay from about 10 PM-midnight with copious amounts of lightning and wind gusts in the 30-40 mph range. I set up my video camera on the eastern shore of the Green Bay pointing west/southwest.

Spring Arriveth

You know it's spring when...

...first day you can feel comfortable outdoors without a sweatshirt
...there are big flies buzzing around in the weight room again (probably the offspring of the ones that were buzzing around in there until late October last year)
...daffodils, crocuses and Easter bunnies...
















...and the final piece of evidence...

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE UPPER MS VALLEY INTO THE GREAT LAKES...

This is for tomorrow. The main risk is for hail from elevated storms, but with strong deep-layer shear they will probably be supercellular and quite photogenic (if they can form discrete cells instead of one giant convective mess). I can't chase because I have class in the late afternoon, but with luck I will at least be able to see a decent thunderstorm, which would be the first since March 11th.

Weather Event #9-April Strikes Again

Reports on April 06-07 Severe Weather Events (Updated April 12, 2006)

Yet another potent extratropical cyclone crossed the United States during this period and interacted with sufficiently unstable air for severe thunderstorms and tornadoes. An F2 tornado hit Washington County, Kansas on April 6th and preliminary reports indicate several destructive tornadoes across Tennssee, Mississippi and Alabama on the 7th. The National Weather Service offices have yet to survey these damage paths, so a lot more information will be forthcoming. Both days also received a "high risk" forecast from the Storm Prediction Center, so more information about them will be available in my archive when that is next updated.
