Area forecast discussion, Jul 8, 3:01 AM MDT, 10 hours 7 minutes before
Area Forecast Discussion National Weather Service Pocatello ID 301 AM MDT Mon Jul 8 2019 .DISCUSSION...A cold front remains on track to pass through Southeast Idaho today, allowing for a cooler, cloudy day. Better chances for precipitation are forecast today, particularly late this morning through early this evening. Showers and thunderstorms will track through the Central Mountains and Eastern Magic Valley areas this morning with isolated thunderstorms possible in Eastern Idaho this morning; then track to the east/northeast. Rainfall amounts have not changed much from yesterdays forecast; although there is increased amounts of QPF noted in the Arco Desert and the Southern Highlands with continued good agreement in forecast models in the Island Park/Driggs area of around one-quarter inch of rain in these areas (and the potential for higher amounts in stronger cells). QPF during this event may reach one- half inch in some of these areas. PW across our area is elevated in the 0.7 to 0.9 inch range (in the 90+% of normal range for us), which may lead to heavy rain in some thunderstorms and thus the potential for flooding. It is definitely is something to monitor should the stronger storms reach urban areas today. Small hail and gusty winds will be possible in any thunderstorms today as well. Activity is expected to generally improve near sunset though some showers and thunderstorms may continue through the overnight hours; therefore we have kept a mention of isolated thunderstorms in the forecast. Tuesday will be a transition day between low pressure exiting to the northeast and high pressure building in from the south. Gradual increases to temperatures are forecast Tuesday with much warmer temperatures expected in the middle portion of the week. Look for mid 90 degree temperatures, little chance for precip and drying conditions. NP .AVIATION... Will have generally widespread VFR conditions today with the main impact being mainly afternoon shower and thunderstorm development. For now have vicinity thunder at all TAF sites after 19z through 04z this evening. Any site could see a thunderstorm or rain shower this afternoon with lower ceilings but even those should stay VFR. Expect no shower or thunderstorm activity on Tuesday. GK && .FIRE WEATHER... Main impact today will be afternoon thunderstorm development. Have a red flag warning in effect for zones 425 and 410 for scattered thunderstorms. Will have the storms in all zones but fuels still are not critical in those zones so have limited the red flag for only the two zones. It will be much cooler today with minimum humidities expected to remain well above 20 percent in all zones. Will begin a rapid warming trend Tuesday with dry conditions expected both Tuesday and Wednesday. Minimum humidity will drop to the 15 to 25 percent range Tuesday with many regions in the 10 to 20 percent range on Wednesday as low level high temperatures reach the 90s in many locations. Could see isolated thunderstorms return Thursday and Friday mainly in zones 475 and 476. Expecting strongest winds today in zone 425 where gusts may increase to the 20 to 25 mph range late this afternoon. GK && .PIH WATCHES/WARNINGS/ADVISORIES... Red Flag Warning from 2 PM this afternoon to 9 PM MDT this evening for IDZ410-425. &&
