July 2007 ended on another hot and humid day over southern MB with temperatures of 33-36C and dewpoints in the 22-26C range to produce humidex values of 43-48C. A cold front approaching from the northwest is producing a few intense thunderstorms mainly northwest of Winnipeg. The cell north of Gimli even showed signs of tornadic potential. Additional storms are likely through this evening and tonight as the front moves through southern MB. Some of these storms will be severe with strong winds, hail and torrential rain. The front will usher in less humid and more comfortable conditions across southern Mb for Wednesday.

An outflow boundary can be seen on RADAR from Gimli to just south of Portage at 6:40 PM. A few cells have already formed overcoming the warm air aloft.

Yeah, I saw those.. but they just couldn't get going. I guess it's still too warm aloft here. Nice cells west of us though south of Boissevain and over ern SK near Yorkton where the cap is weaker.. perhaps they'll survive long enough to give Winnipeg a good storm overnight.
ReplyDeleteSo much for an early cool down...as you said those initial storms fizzled under the strong cap. Winnipeg will have to wait for the main cold front and better dynamics lagging behind to get showers. Too bad for those without A/C ... one more hot evening!
