Weather Outlook April 17


The northern-half of the U.S. just won`t be able to shake out of its winter-slump today. Highlights include a flooding rain exiting New England, accumulating snow from the Great Lakes into the northern High Plains and rain and snow spreading across California and the Great Basin.

A powerful low pressure spinning away from the northern Great Lakes will produce a windswept, heavy rain across New England.

The heaviest rain will exit the highly populated Interstate 95 corridor by later this morning. The torrential rain combined with warmer temperatures will result in rapid snowmelt across the Green and White Mountains in northern New England, increasing the threat of flash flooding.

Otherwise, Saturday`s drenching rain across the Great Lakes is being replaced by winter`s chill and a mixture of snow and rain showers today. The mercury will only manage the 30s and 40s from the Great Lakes into northern New England, while warmer 50s and lower 60s grace the highly populated Interstate 95 corridor in the Northeast. Not to be outdone by New England`s stormy weather, northern parts of the Golden State into the Great Basin, central Rockies and along the northern High Plains are having their own slate full of weather.

Everything from valley rain to accumulating wet snow will be common. Even though only a few inches of accumulation are likely, travel will be treacherous along Interstates 90 and 94 headed across Montana and into North Dakota. Meanwhile, similar totals can be expected along the snow-capped higher terrain in the central Great Basin and Rockies.

The coolest temperatures will be confined to the higher terrain across the West and along the northern High Plains, with 30s and 40s likely. Elsewhere, temperatures will reach the 40s and 50s from the Northwest into the northern Rockies, while warmer 60s and 70s will stretch from northern California into the central Rockies.

The southern Plains into the Deep South will be able to breathe a sigh of relief from the recent string of severe weather outbreaks. A sunshine-filled sky combined with summertime warmth will aid in the cleanup process today. The mercury will rise into the 60s, 70s and 80s. Even a few lower 90s will be likely across the sizzling Desert Southwest and along the Rio Grande Valley in western Texas.
