Best time lapse I've seen so far.    

February 15th Storm   Hello All,   Well its been quite a few weeks lately, we've had huge amounts of snow here in New Brunswick, the most I've seen in the 8 years I have lived here. I think in les

I wish our downgrades were like that

I assume at your altitude its not that unusual for late April ?

Is there a canadian weather forum ?

Hi

This time of year its usual. The heavest snowfalls I have seen are in April and May, and sometimes to a lesser extent November. Our biggest snowfall in recent years was early May 2008 when we had 2 1/2 feet fo snow in 24 hours.

There is a canadian weather forum but there are hardly any members that post in there, hence I love coming into this website

Monday May 9th - 1st time in 7 months it got above 15oC

Sicne then its been glorious sunshine and getting warmer every day.

Yesterday was 19oC, today should be 21-22oC. It's a most welcome change after such a long Fall/Winter/Cold Spring

Looks fairly quiet for the next 48hrs.

DAY 2 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 1201 AM CDT WED MAY 18 2011 VALID 191200Z - 201200Z ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE CNTRL AND SRN PLAINS... ...CNTRL/SRN PLAINS... 00Z NAM/GFS ARE VERY SIMILAR IN THEIR PROGRESSION OF UPPER TROUGH ACROSS THE INTER-MOUNTAIN REGION INTO THE CNTRL/SRN ROCKIES BY THE END OF THE PERIOD. ALTHOUGH BOTH MODELS ARE SLOW TO MOVE THIS FEATURE INTO THE HIGH PLAINS EACH IS VERY CONSISTENT REGARDING THE EJECTION OF A STRONG SPEED MAX THROUGH THE BASE OF THE TROUGH ACROSS NERN NM INTO SWRN KS BY 20/00Z. AS A RESULT...DEEP LAYER SHEAR IS EXPECTED TO INCREASE AS 50-70KT AT H5 BEGINS TO OVERSPREAD THE DRYLINE AT PEAK HEATING. LARGE SCALE FORCING DICTATES THAT A PRONOUNCED DRYLINE SHOULD EXTEND SWD FROM A SFC LOW OVER SWRN KS...ALONG THE TX/OK BORDER INTO NWRN TX. WITH STRONG BOUNDARY LAYER HEATING EXPECTED ALONG/WEST OF THE WIND SHIFT SFC PARCELS SHOULD EASILY REACH THEIR CONVECTIVE TEMPERATURE AND ISOLATED THUNDERSTORMS SHOULD DEVELOP AFTER 21Z. WITH MULTIPLE DAYS OF SLY FLOW ACROSS THE PLAINS AND MORE FAVORABLE TRAJECTORIES ACROSS THE GULF OF MEXICO...IT APPEARS BOUNDARY LAYER MOISTURE WILL MORE READILY REFLECT A MODIFIED MARITIME AIRMASS WITH SFC DEW POINTS EXPECTED TO RISE THROUGH THE MID 60S SOUTH OF THE WARM FRONT. BY PEAK HEATING THE WARM FRONT SHOULD HAVE RETREATED TO NEAR I-70 ACROSS KS AND THIS SHOULD SERVE AS THE FOCUS FOR THE MORE CONCENTRATED SEVERE CONVECTION DURING THE LATTER HALF OF THE PERIOD. LATEST THINKING IS ELEVATED CONVECTION WILL BE ONGOING AT THE BEGINNING OF THE PERIOD ACROSS THE CNTRL PLAINS ALONG NOSE OF LLJ. AND ELEVATED INSTABILITY COULD EASILY SUPPORT MARGINALLY SEVERE HAIL...OR PERHAPS AN ISOLATED EVENT IN EXCESS OF ONE INCH. HOWEVER...THE GREATER SUPERCELL SEVERE THREAT WILL EVOLVE AFTER 21Z ALONG THE DRYLINE OVER SWRN KS INTO WRN OK. THIS WILL BE DRIVEN BY STRONG HEATING WHICH SHOULD YIELD SBCAPE VALUES IN EXCESS OF 2000 J/KG ALONG WRN PLUME OF RICHER MOISTURE RETURN. FORECAST SOUNDINGS STRONGLY SUGGEST SIGNIFICANT HAIL IN EXCESS OF 2 INCHES MAY BE NOTED WITH THESE SUPERCELL STRUCTURES. OF PARTICULAR CONCERN WILL BE JUST EAST OF THE DRYLINE ACROSS SWRN KS INTO NWRN OK WHERE BOUNDARY LAYER RH VALUES WILL SUPPORT LOWER CLOUD BASES. THIS MOIST ENVIRONMENT WILL FAVOR TORNADO DEVELOPMENT AS MID LEVEL SPEED MAX OVERSPREADS CONVECTION DURING THE EVENING HOURS. SEVERE THREAT SHOULD CONCENTRATE ALONG THE WARM FRONT AFTER DARK AS LLJ IN EXCESS OF 50KT IMPINGES ON E-W BOUNDARY. ...MIDDLE ATLANTIC... SLOW MOVING UPPER LOW WILL BE SHUNTED EAST INTO THE DELMARVA BY 20/12Z. THIS FEATURE HAS INDUCED STRONG AFTERNOON CONVECTION ALONG THE ERN PERIPHERY ACROSS THE MIDDLE ATLANTIC THE LAST FEW DAYS AND SHOULD DO SO AGAIN THROUGH DAY1 INTO THE DAY2 PERIOD. DIURNAL HEATING WILL PROVE INSTRUMENTAL IN ROBUST THUNDERSTORM DEVELOPMENT BENEATH COLD MID LEVEL POCKET. A FEW STORMS MAY PRODUCE HAIL OR GUSTY WINDS. ..DARROW.. 05/18/2011

THe main weather in he US at the moment is in Montana associated with an area of low pressure. In particular around Great Falls and Billings.

There is currently some severe weather in Illinois and Michigan associated with a low pressure area over the Great Lakes.

Not much weather around at the moment but what there is is concentrated around the S. dakota-Indiana border as can be seen on the Sioux Falls radar. Fortunately not as bad for Aberdeen, to the west of Sioux Falls, this time around.

It was four years ago last monrh during a 48-hour period beginning on the morning of Friday, May 4, and ending on the morning of Sunday, May 6, Aberdeen received 9.12 inches (232 mm) of precipitation. This rain flooded city streets, making many of them impassable for a short time, and caused water damage to many homes. Within 2 weeks of the storm, over 300 families had requested assistance from disaster response agencies. By May 25, 104 houses had been condemned due to the damage; of these, 47 were declared unlivable. Brown County, which includes Aberdeen, was declared a disaster area.

Hi there,

I took this video of a pretty extreme summer afternoon storm in Ottawa, ON, Canada. I had just been outside, walking around in 33 degree weather, came back inside for about 15 minutes, and this ensued:

The CBC news snagged this video from youtube and used it behind the anchor during the story for these storms :p

Levee broken in Iowa:

Posted Image

A levee on the flood-swollen Missouri River near Hamburg, Iowa failed on Monday, sending water into low-lying farmland and prompting a flash flood watch for the town of 1,200, authorities said. The U.S. Army Corps of Engineers said the fight against the rising waters, which is expected to drag on for weeks, would be complicated in the coming days by thunderstorms, some expected to drop as much as 5 inches (13 cm) of rain in places.

Monday's breach in the levee built in the late 1940s was 300 feet (90 meters) wide, the Corps said in a statement. The workers who were on the levee were evacuated safely. In addition to Hamburg, areas threatened with flooding as a result of Monday's levee break include parts of Interstate 29 and the rural residences and county roads located between the Missouri River and Hamburg, the National Weather Service said.

R.D. Hendrickson, in Hamburg from Phoenix to help his family prepare for possible flooding, witnessed the breach on Monday morning south of the town in an area of farms. "It was surreal to see the river take the levee out," he said. "The water was shooting out of the ground straight up and it just cut the levee out. ... Farmers lost their entire crop out there on this one."

Downtown Hamburg, located about 5 miles (8 km) away from the breach, remained dry six hours after the levee failed but vulnerable because of its low-land topography. City officials were warning those who stay behind that within 24 hours the waters would reach the secondary berm hastily built in recent days to protect the city, and that power was likely to be quickly lost when they did. The Missouri River basin forms the northwest portion of the Mississippi River basin that stretches from Montana to western New York and funnels water south into the Gulf of Mexico.

Heavy winter snowmelt feeding the river's headwaters in the Rocky Mountains, as well as heavy spring rains, have forced the Corps to release water from stressed reservoirs and dams up and down the river. The flooding along the Missouri has already displaced thousands of people in South Dakota and threatens to add to the misery downstream in the Mississippi Valley, where record floods this spring caused billions of dollars in damage.

The severe weather in Missouri and southern Illinois continues with severe thunderstrorms and even a tornado on the St. Louis radar. They must have had a fair dollop of rain in the last three or four days so little wonder there are flood warnings out.
