A large, dynamic weather system is churning through the southwest United States and play a significant role in Nebraska’s weather this weekend. Ahead of the system, thunderstorms have developed in the Texas panhandle, requiring Tornado Warnings to be issued.
A plume of moisture can be seen in the satellite image above. It runs from the Gulf of California, through Mexico, Texas, Oklahoma, Kansas, and Nebraska. It is being drawn up ahead of the upper-level low that resides over southern Nevada, Arizona, and California.
The moisture streaming north in to the central United States is priming the atmosphere for a large rain and snow maker.
Rain will arrive in southeast Nebraska as early as Saturday morning, reaching the Lincoln area by midday. From that point forward, rain will remain in the forecast through Monday morning. At times the rain could be very heavy, especially late Saturday night and Sunday. A widespread 2″ to 3″ of rain looks possible through Sunday night for the Cornhusker state.
A 3-computer model average suggests 2.82″ of rain for Lincoln. There are several things of interest about that.
- Lincoln has received 2.32″ of precipitation for the year so far. We could double that in two days!
- The record 2-day rainfall for March is 2.62″ on March 22-23, 1987. We could break that.
- The record rainfall for Sunday is 0.86″ set in 1913. We will likely smash that.
DON’T HEAD WEST YOUNG MAN
Traveling through western Nebraska, Colorado, and southeast Wyoming is not advised this weekend. Heavy snow is likely starting as early as Friday night. Blizzard Warnings, Winter Storm Warnings, and Winter Storm Watches have been issued in advance of the storm hitting.
Some areas of western Nebraska could receive as much as a foot of snow by Sunday night. Further west, portions of southeast Wyoming could receive 1 to 3 feet of snow. Further southwest, areas along the front range of the Rocky Mountains could receive 6″ to 20″ of snow and higher in the mountains could receive 3 to 4 feet of snow.
