A series of storm systems will be impacting the West through the weekend and into early next week.
Showers, with mountain snow, are possible today with the first in the series of systems with a brief break in the precipitation before the next one moves ashore tonight into tomorrow.
Some locally heavy rain and snow is possible.
Winter storm watches are posted for portions of the Sierra Nevada Mountains, with a flash flood watch posted for the northern end of the Sacramento Valley.
On Monday, yet another system will make its way inland, bringing snow levels down as much cooler air begins to slowly move into the West.
Unsettled weather is expected to continue in the Pacific Northwest through midweek.
Ahead of the systems, warmer than average temperatures are expected to continue through the weekend.
Highs today will range from the 30s and 40s in the Cascades and Sierra Nevadas to the mid 90s in the Lower Colorado River Valley.
High pressure over the Carolinas will help keep much of the South dry today and allow southerly winds over the Southern Plains and Lower Mississippi Valley to warm temperatures up.
Along Florida's East Coast, onshore winds will bring a few showers to coastal areas through the weekend as well as an elevated risk of rip currents.
In the Ozarks, an upper level disturbance may bring a stray shower or thunderstorm, but most areas will stay dry and only see an increase in cloud cover.
Shower and thunderstorm chances will continue along Florida's East Coast and begin to spread across the Peninsula as an area of low pressure is forecast to develop and move out to sea early next week.
A developing storm in the High Plains early in the week will bring gusty winds to the Southern Plains, and possibly a chance of rain to the Ozarks and Lower Mississippi Valley by midweek.
Highs today will range from the 60s in most of Virginia and North Carolina to the mid 80s in Texas.
A warm afternoon is forecast for the Midwest today, with plenty of sunshine.
A few clouds and a storm or two is possible near the Ozarks from an upper level disturbance moving through.
A dry cold front will bring cooler temperatures to areas near the Great Lakes tomorrow, and another cold front with an upper level trough will bring some showers and gusty winds near the Great Lakes on Sunday.
A storm system is forecast to develop in the High Plains early next week and bring a chance of rain to much of the Plains and Mississippi Valley by midweek.
Highs today will range from around 50 along the Minnesota/Canada border and over much of Upper Michigan to the upper 70s in southwestern Kansas.
The Northeast should enjoy a fairly quiet weather day today with plenty of sunshine.
Clouds will increase late today ahead of a cold front, with a slight chance of a shower or two in the interior tonight and tomorrow.
Cooler temperatures will move in by Sunday.
Another front and upper trough moving out of the Great Lakes will bring a chance of showers to Upstate New York and New England by Monday, with warming temperatures by midweek.
Highs today will range from the mid 40s in northern Maine to the low 70s in western West Virginia.
