A Long Week With Chances Of High Impact Weather Increasing.
High Impact Weather Briefing Sunday Morning.... This is for the entire week. There is a lot of information here so bare with us.
This forecast covers the week of 2/17 - 2/24/19.
The first three graphics are our key messages for this week's weather.
Periodic influxes of moisture from the Eastern Pacific aloft and the Gulf of Mexico at the surface are expected between stagnant upper level through in the west and a strong subtropical ridge near the Bahamas. These factors should lead to 5-10 inches of rainfall accumulations across portions of the southeast and mid-south into next Sunday.
This is a tale of three storm systems and we will likely add to that number being honest.
1) NW Mountains sections of Burke, Caldwell, and McDowell will see scattered precipitation move int o the area Sunday as a weak high pressure ejects out of the Midwest into Tennessee. NW Burke, NW Caldwell, and NW McDowell will see this precipitation fall in the form of freezing rain. This freezing rain will cause mainly just travel issues.
2) Low Pressure will develop over the southwestern gulf coast spreading moisture North Tuesday Night. High pressure to the north will funnel dry cold air at the surface down the Eastern Slopes of the mountains briefly Tuesday Night into Wednesday Morning. Precipitation types could be an issue for about a 12 hour period along and North of I-40 primarily but also possible in the remainder of the foothill locations.
3) After precipitation transitions from anything frozen to liquid the rainfall will continue. Additional waves of low pressure will move through from Southwest to Northeast. The heaviest rain could fall between Thursday, Friday, and Saturday creating the risk for flash flooding.
***People living in the mountains and foothills should monitor the potential for heavy rainfall that could cause flash flooding and winter weather that could impact utilities and travel. Monitor later forecasts and updates as these events unfold.
Most of the graphics are pretty self explanatory but if you have questions don't hesitate to ask.
