So far this summer, temperatures have reached 94-98 degrees, with heat index peaks of 101-117 degrees. The highest heat index was ahead of the Progressive Derecho, with dew point reaching an incredible 78-84 levels. It's very oppressive air that takes your breath away.
It's July 20th, there are 11 days left in the month, 31 days left in August, and the 90s are typically seen in the first half of September. In any case, they are not over yet. However, we now have some breathing space.
Lows this morning are not as cool as Friday morning 49-57. Their score fell to 52-58 this morning.
The high temperature will reach 77-83 degrees on Saturday, with partly cloudy skies and low humidity.
Thicker wildfire smoke from the Northern Rockies and Western Canada is bringing us hazy, pale skies late Sunday into Monday and beyond. We will monitor smoke thickness and its depth in the troposphere. Due to its capping trend, it may affect shower and storm coverage.
Some smoke may mix to the surface, causing air quality to deteriorate at times next week.
An impressive Saharan dust storm will bring dust to our region early this week. Some of this will mix to the ground, especially given the showers and storms surrounding it. We need to monitor this dust. It can reduce rainfall coverage.
Smoke and dust will remain a problem until the end of July. Dust and smoke problems tend to peak with hot, dry weather from July 26-31. This will result in significant deterioration in air quality, especially for sensitive individuals suffering from asthma, COPD and/or other respiratory conditions.
We have two higher lows tending to merge into one low from Monday afternoon into Thursday noon.
The experience is this:
1. There will be scattered showers and storms on Monday. The weather was mostly cloudy to cloudy in the morning, with showers southeast of the viewing area, and we saw a combination of clear skies and cumulus clouds. These bubbles can create some scattered showers and storms. Given the rotation associated with the approach to the upper low, cooling air aloft and dew points rising to 65-70 with a high of 81-85, the possibility of a few funnels or landspouts cannot be ruled out.
2. After the rain ends, we will see some scattered fog Monday night into Tuesday morning, with partly to mostly cloudy skies, and only some scattered showers and storms looking like Tuesday. Most of the area remains dry. It does look humid due to the sun and cumulus clouds. Highs are expected to be 82-86, with a heat index of 85-90.
3. Tuesday night into Wednesday morning, mostly cloudy skies and 60s, after some scattered fog. Rainfall will increase on Wednesday. Scattered showers and storms will develop during the afternoon and evening. Highs are expected to be 79-84, with a humid to muggy dew point of 66-71. Isolated random funnels or terrestrial vents are possible.
4. From Wednesday night to Thursday noon, there may be scattered showers, then the sun will come out and there will be cumulus clouds. From Thursday afternoon to evening, there will be west to northwest wind, and the humidity will drop slightly. Highs are expected to be 81-85 and dew point will drop from 68-72 to 62-66.
5. Rainfall varies greatly, with rainfall amounts ranging from 0.15 to 1 inch sometimes occurring.
6. The weather is dry, with a maximum temperature of 82-86 degrees, sunny, with cumulus clouds, and a dew point of 64-68 degrees. So, it will be relatively humid.
We will then be dry and the hot upper ridge coming from the northwest will dominate our weather for 4-5 days. It gets hotter at 90 degrees, with a heat index of 90 degrees to +100.
A cold front is approaching and some storms may pass around July 31st.
