Trouble is brewing for Thanksgiving travel as a storm system begins to hit the U.S. this weekend and moves east in the days leading up to the holiday.
The storm began off the West Coast and is expected to produce wet weather as it moves across the country over the next few days.
On Sunday, the Pacific Northwest will face a rainy day with a chance of snow in the higher elevations of the mountains as a storm system moves ashore, making travel through some of the passes difficult. tallest mountain in Cascades in Oregon and southern Washington.
In the Plains, a second system will bring isolated thunderstorms over parts of Oklahoma. Widespread instability does not appear to be in the cards, which is typically an important ingredient for a severe weather outbreak. However, computer forecast models show that there will be abundant moisture, which is another catalyst for shower and thunderstorm activity. Any storm could cause gusts of wind and small hail.
The communities around Oklahoma City and Tulsa have the highest potential for thunderstorm activity.

Monday: Severe storm threat moves into Lower Mississippi Valley
Wet weather will be possible Monday from the Rocky Mountains through the Gulf Coast to the Tennessee and Ohio Valleys and the Southeast.
The weather with the greatest potential to create problems will be along the Gulf Coast. According to the FOX Forecast Center, severe thunderstorms will be possible Monday afternoon and into Monday night from eastern Texas to parts of the lower Mississippi Valley and the Southeast.
The main concerns are expected to be damaging wind gusts and some tornadoes, although isolated hail is also possible. Communities such as Jackson in Mississippi and Baton Rouge in Louisiana are at Level 2 out of 5 on the NOAA Storm Prediction Center’s severe weather risk scale.

Tuesday: More widespread travel impacts expected
On Tuesday, the powerful storm moves east, creating what is forecast to be the worst day of the week to impact travel.
Widespread rainfall is expected across much of the eastern U.S. as the primary system moves into the Ohio Valley, and then a secondary system from Canada will move south, providing additional boost to the ongoing storm .
This will allow light snow to fall on the northern edge of the storm across the Great Lakes and into the higher terrain of upstate New York and northern New England, but it is too early to determine how much accumulation is expected, according to FOX. Forecast Center.
This storm is of Pacific origin, with limited cold air to work with, so it will feature mostly rain elsewhere.
Rain will reach the Interstate 95 corridor in the mid-Atlantic and Northeast Tuesday afternoon or evening and slide east across the region into Wednesday morning.
Meanwhile, communities between New Orleans and Nashville, Tennessee, face the possibility of seeing an inch or two of much-needed rain for the drought-stricken region.
Wednesday and Thanksgiving: Gradually drying out
On Wednesday, one of the busiest travel days of the year, the storm system is expected to gradually slide off the East Coast, drying rain from west to east during the day in the Northeast, although forecast models diverge on the speed with which the system advances. It moves east and off the coast.

A slower system would continue to bring rain to much of the East Coast, while a faster system could bring dry conditions by Wednesday, the FOX Forecast Center says.
Overall, Thanksgiving looks quiet across much of the country, with only some snow in the Northern Rockies and periods of rain in Texas.
But forecast models diverge in their long-term forecasts for what will happen after Thanksgiving and people will begin their journey home. There is a possibility that a second system could develop in the wake of Wednesday’s storm, moving across the central US on Friday and affecting the eastern US next weekend. The details will be better defined in the coming days.
