Hermine lashes South Texas

Tropical storm Hermine has moved inland over extreme southern Texas this morning heading northward. The storm was nearing hurricane strength with winds gusting over 70mph as it made landfall in northern Mexico overnight. Hermine has been delivering strong winds in the 30 to 50mph range with rainfall of 1-3 inches per hour in the heaviest bands. Isolated tornadoes have also been reported in coastal Cameron County. Hermine will slowly move northward today across the Lone Star state with heavy rain as far north as Dallas expected. The rest of the Atlantic basin is quiet today.

Montreal: Some showers are moving across southern Quebec this morning in response to a warm front lifting north. The front should clear the Valley by noon and for a brief period place us in the warm sector. Partial sunshine and temperatures approaching 25C are likely. This evening a gusty cold front will move through Ontario and Quebec bringing the risk of more showers and thunderstorms along with cooler temperatures. The balance of the week will feature a frontal trough producing fall like unsettled conditions. Plenty of instability will lead to frequent afternoon showers, with temperatures in the 18 to 21C range for daytime highs, and 11 to 15C overnight.

Of note, a sign of the seasons in Alberta with frost warnings in effect tonight for central and southern portions of the province.
