John's Manitoba weather journal: Wednesday, May 18

Rainfall measurements are coming in now and the Winnipeg area did receive some fairly significant totals due to thunderstorms this morning. Rob in Charleswood (@robsobs) measured 24 mm since midday Tuesday and Dale in Island Lakes (@meteo1979) measured about 33 mm as a two day total. As stated yesterday, if we get thunderstorms passing over, amounts of rain can be increased greatly. 

Going forward, a few more showers today but the thunderstorms have ended. We'll even see a bit of clearing tonight which may lead to some patchy fog, mainly in Winnipeg and southeast Manitoba.

Thursday into Friday, we see another low moving in, with another 10-20 millimetres of rain through the Red River Valley. Some of that could be mixed with snow Friday morning in some parts of southern Manitoba. 

The long weekend: Saturday morning starts with a few showers but skies start to brighten in the afternoon. It's still going to be chilly, though, with a highs barely getting past the single digits both Friday and Saturday. 

Sunday and Monday do look a lot brighter with temps in the mid teens. 

People keep asking, "When is it going to warm up?"

I've been looking at some longer-range guidance for temperatures in the eastern Prairies and I don't see us returning to daytime highs of 20 C or warmer until the very end of the month. That's at least two more weeks.
