From KATV, snow falling across Arkansas on Tuesday.

A big swirl of low pressure continues to spin its way northeast across Ontario this morning. On the front side of it in the mild air, Montreal sits at 9C with showers, meanwhile Toronto is down to 2C. We had quite an intense period of rain early this morning here on Ile Perrot, and that pushed my 24 hours rain total to 29.7mm. It has been very wet across Ontario and in some cases white. Yesterday 81.2mm of rain fell in Windsor, with 42mm across the GTA and 21.2mm in Ottawa. The rain has since changed to wet snow across portions of Ontario and southwest into Michigan and Indiana where as much as 25cm (10 inches) fell late yesterday and overnight. The snow has left many without power. It has been a bizarre fall with so may regions receiving wet snowstorms just days after having well above normal temperatures. Snow fell as far south as Arkansas and Mississippi yesterday. Many regions of the deep south were colder than Montreal on Tuesday. The cold is air slowly pouring into eastern Ontario and Quebec this morning on gusty west winds. Look for high temperatures to be reached early in the day in the St. Lawrence Valley followed by a slow fall to overnight lows below freezing to -4C. The showers should taper off to a few flurries by late today. A coupe of centimetres of wet snow may accumulate across the Ottawa Valley.

We will have a brief break on Thursday before another area of low pressure brings a chance for rain and wet snow on Friday. The weekend at this time looks cloudy and cool with flurries.
