8/9/2004 NOW: GREAT LAKES/CANADA

[Robert Dewey]

Watches going up in the Great Lakes, and there is also some action being reported in Canada...

 

[rdale]

GOES rapid-scan showing nice CU development over Wisconsin along the front, with storms gathering a little momentum over northern WI / western UP.

 

[Geoff Boyle]

The Severe T-Storm watch has been extended to another Nova Scotia county in the last hour. Chasers are reporting heaving rain, hail and the odd funnel cloud. The Radar shows scattered cells around. Quite a bit of rain in one area.

 

[Zach Bailey]

Tornado box up for eastern CO, perhaps we want to expand the scope of this NOW thread? Looks like things might be initiating there shortly.

 

[rdale]

CO is not related to the Great Lakes event - that'd get its own thread.

Back home - dew points into the mid-60's now in SW Mich, nice southerly winds ahead of the front and west-southwest behind it over WI. Not bad setup. RUC showing better lapse rates than earlier forecasts.

18Z RUC shows pretty good increase in moisture convergence around 00-03Z across lower MI, with lapse rates steepening... Instability and wind fields still looking good, just need to watch the VIS loop and radar....

 

[Geoff Boyle]

Severe Thunderstorm warnings have been issued for northern Nova Scotia. Heavy rain and hail in excess of 2 centimetres in diameter have been reported. Wind gusts at about 90km/h have also been reported. However it looks like the storms are dying out.

 

[rdale]

Shutting down... all clear here...

 

[Jared Mysko]

Hail in Nova Scotia? That's a bit unusual isn't it? Then again Nova Scotia gets all kinds of crazy weather... radar image looks pretty tame right now even though severe thunderstorm watches are up for both Nova Scotia and Newfoundland.

Yet another forecast gone bust...

 

[Jeremy Lemanski]

very big bust indeed.

 

[mikegeukes]

NWS Grand Rapids Short Term Forecast still
mentions thunderstorms possibe through 9pm
but no mention of anything being severe.

Just when I'm ready to throw in the towel and enjoy the evening - Chicago starts to get active!

 

[Robert Dewey]

Yeah, but I think the potential for anything big is pretty much gone. What a waste of good August wind fields! If it wasn't for the previous storm system (another bust), maybe there would have been more low level moisture to work with...

Just when I'm ready to throw in the towel and enjoy the evening - Chicago starts to get active!

Then again, it does look like some of those cumulus clouds in the past few scans of the SAT could take off...
