[FEMA]

Homeland Security Threat Level: YELLOW (ELEVATED)

Significant National Weather:

West:
The storm moving out of California will bring scattered showers, mountain snow and isolated thunderstorms to the Four Corners region. The next in a series of storms will move into the Pacific Northwest and produce up to a foot of snow in the Cascade and Olympic ranges. Snow showers will fall in the northern Rockies with the heaviest accumulations in northern Idaho. In the lower elevations, up to an inch of rain is forecast from Washington to northern California. The region will see additional precipitation tomorrow but a warming trend will push snow levels above 5,000 feet.
Midwest:
A stalled front will produce rain and thunderstorms from Kansas to the southern Great Lakes and Ohio Valley. Precipitation totals of one to three inches are expected. A few snow showers may fall across the Upper Midwest but the northern portion of the region will be generally dry and cold.
South:
The stalled front will produce rain and thunderstorms across the southern Plains to the Tennessee Valley and southern Appalachians. Some of the thunderstorms in the southern Plains, Arkansas and northern Louisiana could become severe with tornadoes, damaging wind gusts and large hail. Areas of heavy precipitation (1â 4 inches) will produce flash flooding. Under high pressure, the Southeast will see only a few rain showers.
Northeast:
The stalled front will produce showers and thunderstorms across the Mid-Atlantic States and as far north the New York City metro area. Up to a half inch of rain could fall from West Virginia to New Jersey. Upstate New York and New England will be dry and cold with lows in the teens and low 20s near the Canadian border. Heavier rain is forecast tomorrow for much of the region.
Space Weather:

No space weather storms were observed during the past 24 hours and none are predicted.Â*
Tropical Weather Outlook

Atlantic / Caribbean / Gulf
Area 1
A broad low pressure system located about 850 miles northeast of the Leeward Islands continues to produce a large area of cloudiness, showers and a few thunderstorms mainly to the north and east of its center. This system is forecast to strengthen and produce Gale-force winds over the next couple of days. It is possible that the low could gradually acquire subtropical characteristics before it moves over cooler water. This system has a medium chance (40 percent) of becoming a subtropical cyclone during the next 48 hours as it moves north-northeastward at 10 to 15 mph.
Eastern Pacific
Tropical Storm Kenneth
At 4:00 a.m. EST, the center of Tropical Storm Kenneth was located about 740 miles south of the southern tip of Baja California. TS Kenneth is rapidly strengthening and is expected to become a hurricane later today. TS Kenneth is moving toward the west near 14 mph and this general motion is expected to continue through Tuesday. Maximum sustained winds have increased to near 65 mph, with higher gusts. Tropical-storm-force winds extend outward up to 140 miles mainly northwest and northeast of the center.
