The stormy pattern continues across the northern half of the region today. The main storm system has moved off into western Canada, but showery conditions continue due to an onshore flow from the Pacific Ocean.
Rain and snow should be steadiest and heaviest in the foothills west of the mountain ranges and in the mountain ranges of western Washington, western Oregon and northern and central California today. Rainfall up to 1 inch is possible in the foothills of the Sierras. Elsewhere rainfall should be mostly less than 1/2 inch.
Snowfall should be heaviest in the Sierras and in the Cascade Mountains of Oregon. Accumulations of 5 to 10 inches are possible through Friday morning. Elsewhere accumulations of 3 to 8 inches are forecast.
High temperatures should be mostly in the 30s and 40s in the northern part of the region and in the 60s and 70s to the south. A few areas in southeastern California, southern Arizona and southern New Mexico could reach the 80s this afternoon.
March is known as a fickle and changeable month as the atmosphere goes from the chill of winter to the warmth of summer. After a nice day Wednesday today will feature a return to a mid-winter chill across the region.
Even under sunny to partly cloudy skies temperatures will only reach the single digits and teens in northern New York and northern New England, the 20s to lower 30s over the remainder of New York and New England and the 30s to lower 40s over the rest of the region.
Warmer temperatures return Friday, but so does some rain and snow in western areas of New York, Pennsylvania and West Virginia.
An area of light snow moves through northern Wisconsin and northern Michigan today. Accumulations of 1 to 3 inches are possible, although a few areas along the Wisconsin and Michigan border could pick up 4 or 5 inches.
Areas of freezing drizzle or light freezing rain are possible through the morning hours in eastern South Dakota, eastern Nebraska and Iowa. Significant ice accumulations are not expected, but the freezing drizzle could cause some icy patches on any untreated roadways.
A wintry mix of snow, ice and rain is expected in extreme southern Minnesota, northeastern Iowa and extreme southern Wisconsin this afternoon. No significant snow or ice accumulation is expected.
The same storm may produce a few rain showers over Iowa and northern Illinois this afternoon through tonight.
High temperatures range from the 10s and 20s in North Dakota and northern Minnesota to the 50s and 60s in the Ohio Valley, Missouri and Kansas.
Moisture flowing northward off the Gulf of Mexico may produce a few showers in eastern Louisiana and southern areas of Mississippi and Alabama through tonight. Later this evening and overnight the atmosphere may become unstable enough to allow the showers to grow into thunderstorms in Louisiana and Mississippi.
A few renegade showers are possible throughout the morning and afternoon in southeastern Florida and in the Florida Keys. The passing showers should do little more than cause a brief delay to any outdoor plans.
The remainder of the region will be dry.
High temperatures should be mostly in the 60s in 70s across the region. In western Texas temperatures should climb into the 80s with a few areas possibly approaching 90 degrees near the Rio Grande River. Cooler temperatures will be building into North Carolina with highs only in the 40s in the northeastern part of the state and in the 50s over the rest of the state.
