Thu, Aug 21 - Another hot one; Cool weather coming.

Yesterday we reached a high of 98.5*F on campus. My station at Manti High school reached 100.9*F. This ties the 2nd hottest day this summer. As we approached the peak temperature in the afternoon, clouds moved in. Clouds are great insulators, so they helped the high temperatures to linger for most of the afternoon. The high pressure system that has been sitting over us for weeks is weakening and moving off. As a result, temperatures will start dropping over the weekend and humid air will move into the area, bringing chances for precipitation at least through the middle of next week. High temperatures over the weekend will be in the mid-80's, and the current forecast for next Wednesday is down into the 70's!

Wed, Aug 20 - Hot; Rain coming

Skies have been very clear the last few days. This is due to a high pressure system that is still sitting over us. As a result, temperatures have been more extreme - high 90's in the afternoon, around 50 in the morning. The high pressure is weakening, however. As the weekend approaches, the high pressure system will weaken and move away, allowing humid air from the southwest monsoon into the area. As a result, chances for rain starts increasing tomorrow until we have good chances over the weekend and into next week.

Mon, Aug 18 - We had Rain!!

We had rain this weekend! On Saturday, a thunderstorm formed and made its way down the valley. Rainfall amounts were substantial with 0.25" of rain on campus! Other parts of the valley had more (0.31" in Spring City, 0.54" at a different site in Ephraim, and about 0.5" up Thistle Canyon). The Skyline also had about 0.25" of rain. Looking forward, we may not see as much rain for a few days. A High Pressure system we have been watching was parked over Colorado, bringing humid air from the South. However, this High Pressure system has moved to the West and is now sitting over Central and Eastern Utah. As a result, much of Utah will actually experience very high temperatures for the next couple of days. This system will weaken as the week progresses, however. More of the Southwest Monsoon will extend Northward and reach our area later this week, bringing more rain in the later parts of the week and into the weekend.

Fri, Aug 15 - Increased Cloud Cover - Rain today?

Yesterday was partly cloudy for most of the day, so we didn't get as hot as we did the day before. The clouds are a result of humid air coming from the South. The cloud cover has increased a lot overnight, giving us an even higher low temperature than yesterday. The increased cloud cover brings up the chances for rain today. The National Weather Service predicts a 50% chance that we have rain today and a 60% chance tomorrow. The rain will likely be accompanied with lightning and thunder. Unfortunately, the wind from the South will bring smoke from the Monroe Canyon fire in addition to the humidity. Smoke tends to interfere with the development of thunderstorms, so the rain will likely be limited to today and tomorrow. There will, however, be intermittent chances of rain for the next week.

Tuesday, July 29, 2025 - Smoke is heavy, Winds should change later this week

Image
Smoke from the Monroe Canyon fire is still inundating the Sanpete Valley. With prevailing winds from the South, the smoke is being driven directly into our valley. AQI measurements have peaked over 150 in the area, and we started this morning already over 100. Today will probably be a bad one. The fire has burned an extra 2,000+ acres since yesterday. Containment is still at 16% with an expected containment date around the middle of August. There is hope for us in the next couple of days. First, there is a chance of rain on Thursday. It is not a large chance, but enough that the weather systems with it should clear out the air a bit. But more importantly, the winds will be shifting directions later this week, driving the smoke eastward. But even with that change, we will still be under a large High pressure system that will persist for another week or so. We are looking at another week of hot and dry weather.

Monday, July 28, 2025 - Fires and an Orange Sunrise

This weekend has been filled with a lot of smoke. There are a couple of fires to the South: one in Monroe Canyon (South of Richfield) and another around the Grand Canyon. Prevailing winds are currently from the South, so they are bringing the smoke into the Sanpete Valley. This morning, a thin layer of ash covered cars and sidewalks, and the sun rose a dark orange color. The Monroe Canyon fire is currently only about 15% contained, and isn't expected to be fully contained until the middle of August. The air quality index around here reached just over 150 yesterday, putting us into the Unhealthy index. So, people should limit their time outdoors for the next couple of days. This week is going to continue to look dry. We do have slight chances of rain on Tuesday, Wednesday, and Thursday, but they are just slight chances. But they could, if nothing else, help clear out the air a little.  Day Low (*F) High (*F) Precipitation Yesterday 49.6 89.1 0.00 Today 50.3 96 ...
