Record Breaking Heat (Officially)

WEATHER DISCUSSION

HOT is the word of the week so far and we’re just getting started. Hot air from the south has been moving into our area little-by-little each afternoon. High pressure near Nevada is slowly retrograding back into our region and because of this, hot air is being moved from the Desert Southwest up into our region. Each day may not seem overly different, as the temperatures are moving up slightly by a few degrees each day; but after several days of increases, you can start to take notice that these brutal temperatures are hanging around.

Recorded Temperatures (2014) vs. Records for July 6th.

Recorded Temperatures (2014) vs. Records for July 6th.

A couple of notes to mention with the heat in the area. The record for July 6th in Klamath Falls was 93, set back in 1968. That temperature was tied today. In Alturas, CA, the official record for today was 98, set back in 1984. That record has been surpassed. The new record for July 6th in Alturas is now 99 degrees. So we can officially say, “record-setting” heat in our region.

HEAT ADVISORY starts a noon Monday until 8pm Tuesday.

HEAT ADVISORY starts a noon Monday until 8pm Tuesday.

Now, because we are seeing these hot afternoon temperatures reaching the 100’s, a HEAT ADVISORY is issued for the valleys in Western Siskiyou, Jackson, Josephine, and Eastern Curry Counties. This advisory will start Monday at noon and last until Tuesday at 8 p.m. The highest temperatures in these areas will be topping out between 100 and 106 degrees for both Monday and Tuesday afternoon. It doesn’t stop there. Overnight lows in these regions are not expected to drop below 65 degrees overnight on Monday. So it will be warm overnight and hot in the afternoons. That is why the advisory extends until Tuesday.

A weak cold front will enter the region Tuesday evening and bring with it slightly cooler air. This will lower our temperatures about 5-10 degrees. for the end of the week. We will still be hot in the afternoons, but not in the 100’s like the beginning of the week. With this cooler air, the high pressure ridge will flatten out and shift the upper level flow to come from the south. This will steer in a monsoonal flow and bring in moisture to the area. Instability mixed with the moisture will create afternoon thunderstorms for Northern California, the Cascades, and the Klamath Basin. Dry air at the surface will increase the chance for dry lightning in the region. This, mixed with gusty winds in the afternoons will prompt a FIRE WEATHER WATCH to go into effect Tuesday. As we approach this event, this will be upgraded to a RED FLAG WARNING. We can not rule out the possibility for small hail with these storms as well. The biggest threat though, will be the dry lightning. Just last week, several wildfires were sparked from the thunderstorms that moved through the region. This is almost guaranteed to happen again this week.

We will begin drying out (meaning the areas that will see rain) by the late part of the week. This will also be another opportunity to move in another ridge allowing for clearing and warmer afternoons. Models are suggesting another round of thunderstorms this coming weekend. This chance looks to be more severe than the ones we will see during the week. However, it is too far out to put any real confidence in this pattern so we will have to wait on it and assess the situation.

Thanks for logging on and have a good week!
