Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

Overview

A deep upper level low pressure system setup over the southwest U.S. by Saturday October 6th and allowed unseasonably rich Gulf moisture to stream into the Plains. Multiple rounds of heavy rain affected much of Kansas with the majority of it falling on October 8th and 9th. Most locations received between 4 and 6 inches of rainfall with some locally higher amounts. This lead to widespread flooding across the region. At one point, NWS Wichita had river flood warning for 35 points along with 20 additional areal flood warnings.

Likely even higher now. This is just down 4th Street near Sedgwick High School where the road is closed. pic.twitter.com/sIFZs0b5uw — Melissa Murray (@KWCHMMurray) October 9, 2018	Water is now over the road at 4th Street in Sedgwick right in front of Sedgwick High School. I’ve seen at least half a dozen cars drive through this water in just a few minutes - DON’T do it! You do not know how deep the water is or what’s underneath. pic.twitter.com/OkcpGzn0Rr — Melissa Murray (@KWCHMMurray) October 9, 2018
