100 mm of rain past week..drier and warmer weather next week

It's been a wet week over southern MB with 3 major rain events since last Friday. An average of 100 mm of rain has fallen in Winnipeg over the past 6 days according to city rain gauges, ranging from 80 mm over southwest areas of the city to 115 mm over northeast sections. Here at my site in Charleswood, I've picked up 90 mm since Friday, with 80-85 mm at the Winnipeg airport, and 85 mm at the Forks. This has quickly alleviated any concerns about dry soil conditions across the Red River valley and across Southern MB.. with standing water now appearing in ditches and low lying areas. Amazing how quickly things can change in Southern MB!

The good news is that it looks like drier and warmer weather will be on tap next week, with no major weather systems moving through the Dakotas (a common source for heavy rain in early summer) Hopefully this signals the change to a much needed warm weather pattern over southern MB, which has seen a below normal temperature pattern since April 21st (past 7-8 weeks)

Cool unsettled week ahead

Enjoy the dry weekend.. things will be getting wetter by Monday, with cool and unsettled weather likely most of this week. A system will be crossing southern MB on Monday bringing a general 10-20 mm of rain across the area, with embedded thunderstorms possible. Another system moving across the Northern Plains is expected to bring another shot of rain into southern MB by Wednesday, with 10-20 mm possible again (possibly higher amounts due to convection) June is the wettest month on average in Southern MB as weather systems moving across midcontinent tap increasingly warmer and more humid air from the states and draw it northward, resulting in more frequent showers and thunderstorms across the southern Prairies.

Friday soaker!

A real soaker out there today with wind swept heavy rain falling across Winnipeg and much of Southern MB.  I've received 28 mm as of 8:45 am, about 18 of that in the past couple of hours. City sewers having trouble keeping up with the volume of rain with waterlogged streets everywhere this morning.  Highest amount so far is 42 mm at the CWB site in Glenlea south of Winnipeg.  Radar shows moderate to heavy rain continuing this morning before tapering off this afternoon. With rainfall rates of 5-10 mm per hour in the heaviest bands, we could end up with rainfall totals of 40-60 mm across portions of the Red River valley.   Will try to keep you up to date on rainfall totals as the day progresses.. Feel free to pass along any rainfall reports you have in the comments section.  

Not much rain last night.. Significant rain possible Friday

Well the rain promised for last night and today fizzled over much of southern MB, with only light amounts of 5 mm or less reported in most areas. Here in Winnipeg, we had some light showers move in last evening giving amounts less than 1 mm, but the area of rain quickly dissipated overnight.  Attention now turns to a more potent system developing over the Northern Plains Thursday which has the potential to spread significant rainfall amounts across Southern MB by Friday.  This system will be tapping a warm moist airmass from the southern US, producing numerous showers and thunderstorms over the Northern Plains Thursday along with severe thunderstorms. This area of showers and thunderstorms will be moving northward into southern MB Thursday night into Friday morning, giving heavy rain at times. Models are indicating a potential of 25 mm of rain in most areas by Friday with up to 50 mm possible in more persistent showers and thunderstorms.  So if you're still waiting for a good soaking rain in southern MB.. Friday may be the day! Stay tuned..   

Saturday convection

Just starting a new thread to talk about today's convection.. we're missing out on most of the action here in the southwest part of the city, but some interesting thunderstorm cells off just to our east.
