Moke Impacts Hawaii; Severe Thunderstorms and Heavy Rainfall from the Great Basin to the Plains

Heavy rain from Tropical Storm Moke will begin to impact the Big Island today, risking life-threatening flooding and mudslides in windward and southeast areas. Severe thunderstorms are expected across the northern Rockies/Plains and northern Great Basin. Repeated storms and heavy rainfall may cause flash flooding from the Plains into the Lower MS Valley. Dangerous heat persists across the South. Read More >

Another round of showers and thunderstorms is expected today, with the highest chances concentrated in the Northern Panhandles. Isolated storms could begin as early as 2 PM, with coverage and chances increasing later tonight. Any developing storm will be capable of generating localized heavy rainfall and strong wind gusts.
Widespread triple-digit high temperatures are expected across the Panhandles once again today. Highs in the Eastern Panhandles could reach up to 108°F, while Palo Duro Canyon may see temperatures rise to 111°F. Given the prolonged stretch of triple-digit heat, the risk of heat-related illnesses is increased. Please remain hydrated and take frequent breaks when spending time outdoors.
A subtle shift in the weather pattern is expected to provide increasing chances of thunderstorms across the area this week. Here is what you need to know: The Setup: The high-pressure system currently sitting over us is going to subtly shift to the southwest. This repositioning opens the door for weather disturbances to move through our region. Best Chances for Rain: We will see our highest rain and storm chances on Tuesday (30-70%) and Wednesday (25-55%). Monday and Thursday will also see lower, but still possible, chances for scattered storms. Peak Timing: The most active weather is favored during the evening and overnight hours. Who Sees the Most Rain? Currently, the Northern Panhandles are favored to see the highest rainfall totals, with a good probability of seeing at least ½ inch of rain. Severe Threat: Please stay weather aware, as severe thunderstorms are possible with these systems! Any minor changes in the position of that high-pressure system could shift exactly how far south these storms reach, and weather models can struggle with how fast these persistent heat dome highs move and break down, so we will be keeping a close eye on it. Make sure to check out the attached file for a detailed visual breakdown of the daily rain chances and a map of where we expect the heaviest rainfall.
This week, high temperatures are expected to remain 100+°F across much of the combined Panhandles. Make sure you stay aware during prolonged periods of heat on how to stay safe during outdoor activities!
