After nearly an entire month with no precipitation, this week will bring plenty of rain to the RRV and bring us to the edge of winter.

A powerful low pressure system will move across the RRV tonight and through Tuesday bringing with it plenty of rain.  As the low begins to approach the Ontario border, it will deepen dramatically bring unpleasant conditions to Southern Manitoba.

The rain should begin this evening into the overnight period as the low approaches giving us only about 5-10mm.  As the low passes on Tuesday, winds will shift around to the north and increase to 40 to 50 km/h.  This gusty north wind will whip plenty of rain that will develop along a elongated hang-back trough resulting in blustery, wet conditions amid a dropping temperature through Wednesday.  Total rainfall amounts will probably be in the 15-25mm range, however could be higher in a few places.

Snow looks unlikely for most of the RRV right now, however the rain may switch over to snow for extreme western edges of the RRV on Wednesday as cooler air is able to poke in over the higher terrain.  Accumulations should be somewhat negligible, however.

So, a wet (and soon to be windy) week is ahead of us.  The clouds should clear out Thursday and we will be left with cooler, albeit sunny, weather.
