Our winter storm will begin to get its act together as it develops this Saturday. In the Ohio Valley, colder air will intrude, allowing for snow to fall north of the river, although accumulations will be light and between a coating to two inches for most areas–if anything. It’s not until you get into portions of the Mid-Atlantic and Northeast where significant snowfall is expected as the low pressure develops near the Outer Banks. Snow will break out and move into the Mid-Atlantic region this afternoon. Snow is forecast to fall across eastern Ohio into much of Pennsylvania, New York, and down into portions of Maryland and West Virginia, including Washington D.C., Baltimore, and Philadelphia. By the evening and the first half of Saturday night, the snow will expand eastward as our storm quickly develops just off the coast, into cities like New York, Hartford, and Boston. Snow will begin…

The active weather continues across the Northwest as a new storm moves in this weekend. A very potent upper-level disturbance will drop southward from the Gulf of Alaska, into the Northwest, and eventually into the Southwest US during the start of next week.  It is this disturbance that will bring a widespread snow to the intermountain West, a region that has been experience snowfall deficits so far this winter. On Friday, rain showers will begin to sneak in ahead of the main disturbance into the Washington and Oregon coast while snow falls in portions of the Cascades, mainly in Washington state. A heavy snow is also expected to fall in portions of the northern Rocky Mountains in northern Idaho and western Montana. It’s not until Friday night when the activity will begin to ramp up as our upper-level disturbance takes a southward plunge into the Northwest US. Most of the…

We’re tracking two pieces of energy, each from a different stream within the jet stream. As these two pieces move eastward toward the Central US, they will actual phase, or come together, to eventually produce a winter storm for portions of the Northeast this weekend. Before we get there, this developing storm will bring rain, heavy at times, through the South and into the Ohio River Valley. The activity with this storm will begin Friday in the form of a light to moderate rain across portions of the Southeast US, including southeastern Arizona into southern New Mexico. It’s not until the overnight hours of Friday when the rain expands eastward into the Southern Plains and Mid-Mississippi Valley. Again, this rain will be light so there are no concerns for flooding in this region, besides river flooding. Also the Southern Plains area is desperate for rain, but unfortunately most of this…

A cold front will be pushing south and eastward through the Eastern US heading into the weekend. Expect widespread showers and thunderstorms during much of the weekend. Behind the cold front will be cooler air and a brief reprieve from the active weather as high pressure moves overhead for a very short period. Most of the activity will occur on Friday. On Friday morning a line of rain and embedded thunderstorms with patches of heavier rain will span from southern New England through the Ohio Valley and into portions of the Southern Plains. There may even be a line of thunderstorms ahead of this main line, spanning through the Tennessee Valley and into the ArkLaTex region. Colder air is expected to override the moisture across western and Upstate New York and into northern New England. This will translate to a light to moderate snow during the morning hours before ending…

The end of February sure won’t feel like February overall for the East as a ridge of high pressure dominates the weather pattern. We’re going to discuss what weather you can expect for the rest of this month as well as the start of March. Now the models are still having some trouble predicting what will happen as we get into March, but we’ll discuss the different possible outcomes for you. We’ll also discuss how the precipitation will play out across the country later in this article. Temperature Outlook: For the remainder of the month of February, a ridge of high pressure will be positioned over the Eastern US while a trough sits over the West. With a ridge, that brings sinking air and warmer temperatures, whereas a trough brings rising air and cooler temperatures. This is a classic La Niña pattern. The EPS model below, which is the ensemble…

Following a very wet and soggy weekend, showers will remain prevalent at times across much of the East this week as several disturbances move through the region while moisture flows in from the Gulf of Mexico. On Tuesday, it will be relatively quiet across the East. Spotty showers and isolated thunderstorms are expected in the Carolinas and the southern Appalachian Mountains. To the west, however, the beginning of our next storm system will be in the works will widespread showers and thunderstorms developing as the day progresses in the Southern Plains. From the Mid-Mississippi Valley through eastern Texas, rain at times is expected by the evening hours. It’s not until overnight when the storm will become more organized as it moves east, bringing rain and thunder in the Mid-Mississippi, Ohio River, and Tennessee River Valleys as well as to the Gulf Coast states, including Louisiana, Mississippi, and Alabama. Then on…

It’s been bone dry across the Southwest this winter, allowing for the development of a moderate to severe drought across a significant area. Now even though rain is in the forecast this week, it will be very light and will therefore not ease the drought conditions. On Tuesday, an upper-level low off the coast will steer moisture into portions of the Southwest. Therefore, very spotty light to moderate showers are possible across Southern California, southern Nevada, and Arizona while snow showers are expected in portions of Utah and the Sierra Nevada Mountains. Now on Wednesday, the precipitation will become more widespread as more moisture is funneled into the region. The hotspot of the activity will be focused in Arizona where rain will develop across most of the state by the end of the day. There will also be snow in the higher elevations of the state. Those rain showers will…

The weather pattern will remain quite active for the Northwest and disturbances continue to slam into the region. The weather midweek will be no different with more rain and snow ahead. We’re tracking a quite potent upper-level disturbance that will take a southward dive from the Gulf of Alaska all the way into the Northwest US before stalling over the Southwest US. The weather on Tuesday will remain quiet across the region, although rain showers will likely sneak into northwestern Washington, including Seattle, by the evening. It’s not until overnight when the activity ramps up, as the disturbance plows in. A light to moderate rain will move southward into the Washington and Oregon coasts as the night progresses while heavy snow infiltrates much of the Cascades. Light snow will also be present in eastern Washington, northeast Oregon, the tip of Idaho, and the Bitterroots of Montana. This weather will persist…

Warmer temperatures began this weekend for the East Coast and will continue through much of this week and really through much of the remainder of February as several ridges of high pressure build over the region the next several weeks. Now this week, the overall theme will be for above average temperatures, but there will still be a day or two where there will actually be a cool touch to the air due to brief intrusions of cooler, polar air from Canada. On Sunday, the Central U.S. will be on the cool side as a cold high pressure moves in while the East Coast stays warm due to a strong flow of warm, southerly air. High temperatures in the Northeast will range from the 20s and 30s in northern New England, where snow and freezing rain will fall, to the 40s and 50s in southern New England and the remainder…

Another active weather week is ahead from rounds of showers in the East to rain in the Southwest to a potential winter storm to a spring feel across the East. We compiled a list of the top four weather stories the WeatherOptics team will be watching for you below. Rounds of Showers: Following a very wet weekend for most of the Eastern U.S. it will remain active for the next week. Widely scattered showers and thunderstorms will persist across portions of the Southeast for the first half of the week. Then during the latter half, rain will move into the Northeast as a new storm develops in the Central US. Most of this rain will be lighter compared to the weekend, but clouds and gloomy will be the main story, especially in the South. Stay tuned for this story. Much-Needed Rain for the Southwest: It’s been very dry relative to…
