Widespread frost tonight - weekend update

Widespread frost and freezing temperatures are forecast tonight across southern Quebec, eastern Ontario and New England. A cold front is producing sprinkles and clouds today with dropping temperatures. The high in Montreal will remain around 10C (50F), well below the normal of 21C (70F). Unseasonably cold air will settle into the region tonight with lows of plus 2C to -3C (36F to 27F). The coldest readings will be away from Montreal and any bodies of water. Needless to say if you have planted anything, you should cover them up and take precautions to protect your flowers etc. Frost and freeze advisories are in effect across our entire region with the exception of metro Montreal and Grand Island County, Vermont on Lake Champlain.

The good news is that the cold air will be short lived. A much warmer and sunny weekend is forecast with highs of 18C (65F) Saturday and 24C (76F) Sunday. Next week is looking very summer like with a warm and humid air mass enveloping the northeast and southern Quebec and Ontario. Highs will be in the upper 20's with a risk of showers and thunderstorms each day.

Major flooding is occurring in Texas as heavy rain has pushed accumulation to nearly 20 inches in May. The photo above was taken on Thursday in Fort Worth, Texas, no injuries were reported. (CBS Dallas)

Southern US Flooding
The warm and humid air expected in Montreal next week will be streaming northeast from the US Gulf Coast. Much of Texas, Oklahoma, Louisiana and Arkansas is reporting copious amounts of rainfall for May. Some areas are approaching 20 inches of rain for the month. This region, especially Texas, had been in a major drought throughout 2014. Dallas/Forth Worth recorded only 21.32 inches of rain in all of 2014. So far in 2015 they already have had 21.54 inches with much more forest this weekend. Flash flood watches remain in effect.
