Area Forecast Discussion National Weather Service Pocatello ID 146 PM MDT Sat Jun 27 2020 .SHORT TERM...Tonight through Monday night. Say goodbye to summer, for now anyway. A strong cold front will arrive tonight. Showers and a few thunderstorms will develop this evening. A few storms are developing near the Continental Divide this afternoon, but models aren't showing much south of there until the evening hours. An isolated strong storm with small hail and gusty winds remains possible. Rain will become more widespread across southeast Idaho overnight and into Sunday morning. Much colder air will push into the region. Our highs on Sunday will likely occur during the overnight hours tonight with falling or nearly steady temperatures likely on Sunday. In terms of temperature change, some areas could see a 30 degree difference in temperatures between Saturday and Sunday. A brief dry slot may work into the region Sunday night into Monday. However, we expect more showers associated with the upper low to wrap back into the region for Monday. Is snow possible? Yes, but primarily above 8000 feet where several inches are possible on the highest peaks. In terms of impacts, probably pretty minor with light accumulations possible along Galena Summit. But, pretty nasty weather if one is camping in the high country. In terms of rainfall amounts, we expect up to half of an inch for most locations with some isolated areas possibly receiving amounts around an inch. Probably not a flood concern as most of the snowpack has already melted off. Still, some high flows on smaller streams is possible. Are record temperatures likely? Possibly. We looked at the coldest high temperatures for a few sites and those records could be threatened Monday, but probably not Sunday as the overnight "highs" will probably bail out many locations. In terms of record lows, doubtful, most of the record lows are in the low to mid 30s which leads to the next concern. What about frost/freeze? Right now, clouds and wind may keep lows in the upper 30s to near 40. 13 .LONG TERM...Tue through next Sat. Tue and Wed continues have showers and thunderstorms even into the late night hours as the unstable cold core of the low aloft is re-enforced a little by a second shortwave moving through the longer-wave troughing. By Thu morning, there is signs of the shower and thunderstorm activity being limited to the afternoon and evening, in a more climatic display of convection for the Great Basin. With the storm track staying close by aloft, and the instability continuing during the afternoon and evening, moderate gusty wind will also continue. Once the moisture lessens starting Thu, a stronger warming trend develops for the end of the period as skies are clearer. Temperatures should be back above normal by Fri at the latest--just in time for the holiday. Messick && .AVIATION...An unusual, at least for Idaho, timing for a front and TSRA activity. While some potentially severe TSRA are expected along the ID-MT border this afternoon, but far away from the airdromes, the actual front arrives in eastern Idaho during the late evening hours, approximately 2200 to 0100 tonight. So this will extend the SHRA threat well into the morning hours, and the TSRA develop along the front, so in and around midnight tonight. Not much moisture for these storms, so gusty wind is likeliest issue, along with the wind shear and lightning issues. Shortly after this, moderate to heavy rain develops in the aftermath of the front, especially Sun afternoon, when some marginal VFR could occur. Wind will be much less on Sun compared to the gusty conditions for the late afternoon prior to the front arrival; however the direction will be highly variable, potentially wreaking some mild havoc at KSUN. KDIJ is the most likely to have low CIG issues, and possibly some for with this incoming low. TSRA should return Sun afternoon, but not with the strength expected this afternoon. Messick && .FIRE WEATHER...A breezy and stormy overnight as a front delays its arrival until the middle of the night tonight. Until it arrives, very warm and breezy to windy ahead of the front. This incoming storm is bringing a lot of moisture with it, which means abundant cloud cover, large drop in afternoon high temperatures, by as much as 20 deg F from Sat to Mon, which means high afternoon humidity. Not to mention the potential for moderate to heavy rain. The instability and humidity will continue to plague eastern and central Idaho even during the late night hours until Thu, when the low makes its exit to the north-northeast. This low will even bring SNOW back to the extremely high elevations of the central Idaho mountains. Temperatures will return to above normal by Fri. Messick && .PIH WATCHES/WARNINGS/ADVISORIES... None. &&
