..Spring battles with winter..
---------------------------------------------------------------------
==discussion==
A strong low pressure system over Iowa is approaching the Great Lakes
and will bring quite the variety of weather with it.
Rain in advance of this weather system will continue to move through
Southwestern Ontario this afternoon then advance rapidly northeast
into remaining districts tonight. However over areas near and north
of a line from Sarnia through London to Hamilton, rain will become
mixed with or change over to wet snow for a couple of hours as winter
fights to reestablish a grip on the area. Enough snow to whiten the
ground is possible as far south as the Stratford to Kitchener to
Peterborough and Brockville areas tonight where a couple cm are
possible. Further north and east amounts of near 5 cm expected
overnight into Monday morning.
The wet snow will eventually change over to rain in all regions as a
strong warm front pushes through by Monday, as spring wins this
latest battle with winter. The mercury will rise into the double
digits over all areas except the Ottawa Valley where cooler air will
be more difficult to flush out.
Most regions will receive 15 to 25 millimetres of rain, with locally
higher amounts to 40 millimetres possible. Isolated thunderstorms
may spark some excitement over Southern Ontario tonight especially
near Lake Erie before mild air arrives with the warm front.
As the low tracks over the upper Great Lakes into Quebec Monday a
cold front will bring the brief mild spell to an end and also push
the rain away to the east.
Motorists should be prepared for the possibility of winter driving
conditions tonight into Monday morning in areas that receive wet
snow. Visibility may be reduced significantly in the snow and some
accumulation on untreated roads will be possible.
It's currently 7c under leden skies but as tonight approaches we'll see Heavy rain changing to Wet Snow across much of the GTA for awhile providing very tricky driving conditions. Then, as EC say a change to much milder weather and more Heavy Rain for tomorrow morning. The fireworks come with these extreme changes on climate of a few hours and with it the real potential for some Severe Weather especially Thunderstorms during the transitions from Winter to Spring and then later back to Winter on Monday afternoon.
Flooding could be a problem more so because of the recent snowmelt and then combined 40mm of rain from this system. The same system that is bringing a distict squal line to parts of the Upper Mid-West and into the Chicagoland area with Large Hail, Thunderstorms and even the odd outside chance of a Tornado. This system will also bring Snow to higher elevations of the NorthEast U.S.
Speaking of Tornado's, today marks 37years i believe when on the 3rd of April, 1974 a major historic tornado outbreak occurred across the Mid-West of the U.S. killing dozens but also providing meterologists with vital data to improve Tornado Siren warning times, a process that is still ongoing in 2011.
And finally, hopefully Graeme you've been able to catch the start of the MLB for 2011. The Jays have started on fire with Jose Bautista on-form again and a real spectacular opening to the season with a full house at the Skydome on Honda Opening night. I know it's early, but the T.O. press are positivally 'raving' about the performances and results so far....let's hope they can channel the expectation and continue the fine start. Marketing at the Jays games certainly has improved, they're giving away free Jose Bautista hats and some bats to the first 10,000 punters through the turnstiles. I need to grab one!!!
I've got 3 long awaited and valuable days off this week, so will try and update on the wet and potential stormy weather tomorrow. Take Care
