We’ve complied a look into some of the top stories for this upcoming week. Check them out below. Northeast Rain and Snow Showers A new disturbance will bring a round of rain and snow showers to much of the Northeast to start the new week. Snowfall totals will be light for the most part. Behind this storm will be a return to lake-effect snow on Wednesday. We’ll have a full story on this storm released this Monday. New Storm Enters Northwest As a ridge of high pressure breaks down over the West, a new significant storm will move into the Northwest, bringing a rain and snow event to portions of California. Skiers in the Rockies will also be happy, with widespread snow moving in midweek. Click here for the story. Warm Start for the East The week will be off to a mild start for the East, but another cool down is ahead. Potentially…

The wintery weather will stick around on Monday for western Washington and northern Idaho. Snow will also make way into the Bitterroots of Montana, and a few showers will sneak into northwestern Oregon. On Tuesday, the weather will be the most active, with widespread rain and elevation snow. The reason for this is a direct tap of moisture from Hawaii. There will be a narrow plume of moisture originating from the central Pacific that will make its way into the Pacific Northwest due to steering winds. Rain will start in western Washington, but will spread into western Oregon as the day progresses. Snow will also come down in the Cascades, bringing heavy accumulations, up tp several feet in total from Sunday through Wednesday. Overnight Tuesday, the storm will strengthen. Snow will continue to crank in the Washington Cascades as well as the Oregon Cascades. Rain showers will move into eastern…

The wildfires in Southern California continue to rage on, including the Thomas Fire, which is California’s fourth largest wildfire on record. Luckily during this week, there hasn’t been a major expansion of the active wildfires but that will likely change this weekend as Santa Ana winds peak. Strong winds and low humidity are two of the most important ingredients for wildfires. Both of these will be present this weekend across California with relative humidity values as low as 5 percent. Winds will also gust up to 60 mph in the mountain peaks and up to 40 mph in the lower elevations. These winds will be originating from the intermountain West as a Santa Ana wind event sets up. With this set up, there is a strong high pressure over the interior West. High pressure spins clockwise, so based on its position, it will bring strong winds from the Southwest to…

This weekend, we’ll be keeping an eye on a new disturbance that will track across the Eastern U.S. and around a dome of high pressure over the Southeast. On Saturday, the focus will be on the Texas. Rain will begin to develop by the afternoon across south-central Texas as the low pressure forms. That rain will become more widespread as the evening approaches while moisture gets thrown into the system from the Gulf of Mexico. This rain will move north, expanding into all of eastern and central Texas. Then the rain will move towards Oklahoma and western Arkansas in the evening hours. At this time, the storm will be much more expansive and will begin to turn to the northeast as it rides the high pressure to the south and the east. Overnight, rain will work into eastern Nebraska, all of Arkansas, Missouri, western Louisiana, western portions of Mississippi, Tennessee,…

It’s been quite cold across the East so far this December, but warmer temperatures are ahead for at least a couple days east of the Rockies. This Saturday, warmer than average temperatures will be felt from California, into the Southwest, northern and central Plains, and as far east as the Ohio Valley. Temperatures will be up to twenty degrees with the epicenter of the warmth in Missouri. The exact opposite will be in South Texas where temperatures up to twenty degrees will be below average on Saturday. The only areas feeling the cooler temperatures will be in the Northeast, Northwest, and the East and Gulf Coasts. Then on Sunday, the cold air will still remain stubborn across much of the Northeast. Yet, some of it will sneak into the Mid-Atlantic, as well as in the intermountain West. Meanwhile, the remaining areas east of the Rockies will be feeling the above normal temperatures…

The models this Thursday have suddenly trended towards a weak coastal storm closer to the coast. The models this week have kept this low-pressure far enough offshore to bring zero impacts to the Mid-Atlantic and Northeast. However, every new model run that has come in this Thursday have shown a noticeable trend to the west in terms of the track of this low. Because of this westward shift, impacts from this weak and developing coastal storm are likely. 4-run GFS OP trend valid Friday after sunset. #njwx #nywx pic.twitter.com/puZjGdDES7 — John Homenuk (@jhomenuk) December 14, 2017 A small disturbance from the Rockies will swing through the Southeast and then off the Carolina coast by Friday evening, as shown by the 500 mb vorticity from the GFS model Friday morning. At the same time, a weak area of low pressure will develop off the Carolina coast, leading to the formation of…

Yet another clipper has entered the Great Lakes region from Canada. This clipper system will bring a lighter dose of snow compared to the most recent one, with most areas only picking up to an inch or two of additional snowfall. In terms of timing, on Friday morning a light to moderate snow will be affecting Lower Michigan while the Upper Peninsula deals with lake-effect snow along the northern shore. Along the northern and western coasts of Lower Michigan, the snow will be enhanced by the lakes with the added moisture in place. A light snow will then overspread into northern portions of Ohio and western Pennsylvania during the afternoon hours. Most of that snow will then taper off during the evening. Snow will also move into western New York Friday afternoon, but it will quickly dissipate for the most part and turn into a lake-effect snow event due to…

We are now less than two weeks away from Christmas,  so you may be wondering if you will have a white Christmas. First of all, a white Christmas is defined as having at least one inch of snow on the ground on Christmas Day. Historically, the higher elevations and northern latitudes of the United States have the higher chances for snow on the ground on December 25th. Obviously, in the South, the chances are low for any given year. In the central Plains through the Ohio Valley and into the Mid-Atlantic, the chances are quite low as well, at between 10 and 40%. Of course every year is different, so let’s focus on the actual forecast for Christmas of 2017. This forecast may change, but based on the recent model guidance and analogs, a classic La Niña pattern is expected to set up around Christmas. That means there will be…

Wednesday was brutally cold across the northeastern quadrant of the country, and that cold will persist throughout the weekend for most locations. We’re going to break down the day-by-day forecast through this weekend showing how cold it will get for you. On Thursday morning, low temperatures for many will only be in the single-digits, teens, and twenties for most locations. On top of that, it will feel ten to fifteen degrees cooler than that when you factor in the winds combined with those chilly temperatures. Temperatures in the afternoon will only peak into the 20’s for most areas of the Northeast. Friday will be another chilly day with temperatures similar to Thursday. They will moderate a little, especially in the near the Great Lakes and in northern New England. This is because of the first piece of cold air moving offshore and a second one moving in from Canada, reinforcing…

It’s been a cold start to the month of December, and all indications are for the cold to stick around through the end of this month. One of the main reasons for this chill across the East is because of what’s happening in the West, which is a positive PNA pattern, or Pacific/North American pattern. This type of pattern creates extreme ridging over the West. According to basic physics, what goes up must come down, so while a ridge sits over the West, a trough forms over the East. Based on the PNA forecast from the European model, it continues to show a positive PNA phase through mid-December, then it may actually turn negative for a brief time. That may sound like a complete pattern change but there other factors that play a role into the current pattern across the nation. Therefore, the general theme of a ridge over the…
