If you thought the flooding was fun...

-------------------
A Colorado low located over Nebraska late this afternoon is giving rain, snow, and thunderstorms throughout the north-central United States. Rain from this system will move into southeastern Manitoba this evening, then snow will move into southwestern regions overnight. A narrow band of freezing rain may also set up near the rain-snow boundary overnight and Tuesday over south-central Manitoba.
On Tuesday as this system moves into northern Minnesota, colder air will be drawn in from the northwest and the rain over southeastern regions will change over to snow. This changeover is expected to take place Tuesday afternoon at Winnipeg and Tuesday night over the southeast corner.
Rainfall amounts will be significant for this time of year, especially given the current flooding concerns. 20 to 40 mm are expected for areas southeast of Winnipeg with the highest amounts likely near the american border. After the changeover to snow, a further 5 to 15 cm of snow are likely with snowfall amounts diminishing as you go southeast from Winnipeg. Snow over southern Manitoba will likely persist through Wednesday and possibly into Thursday, however snowfall rates will gradually diminish with time.
Current indications are that the heaviest snowfall amounts will be from Portage la Prairie southwest to the Turtle Mountains where totals may range from 20 to 25 cm, then amounts should gradually diminish through the Gimli and Bissett regions. Strong north winds will also give blowing snow and poor visibilities to many areas.
