Good afternoon, Foothills Weather Nation!
It's a bit hot out there today with our daily high in the low to mid 80's, but it will only be like this for a couple more days before we will return to some "cooler" temperatures in the 70's. So what changes?
Right now we have a high pressure centered over the Southeastern US that is very similar to the one we saw back in February that brought along plenty of unseasonable warmth. This high pressure was more or less advected by a strong ridge that propagated into the region, but now we are beginning to see our ridge flatten a tad as a "summer-y" trough begins to carve away at it's edges as the trough slowly trudges across the Great Plains today on through Friday. With that being said, we're likely to see temperatures in the mid 80's on through Friday.
Starting Saturday our trough will begin to make it's impacts as a "river" of moisture pours over the eastern side of the Appalachians bringing in overcast conditions for Saturday and precipitation probabilities that will ramp up as we go through the day. At this time we don't see any threats of severe weather with this frontal passage, so for now we can assume it will be strictly a rain event with possibly a bit of wind and possibly some lightning. This rain event is likely to hold out on through Sunday where it will begin to taper off to 30% in the pm hours. Current predictions have rainfall totals at a quarter to a half an inch, but is likely to change. Temperatures on Saturday and Sunday will be in the upper and mid 70's respectively for the diurnal high, upper and mid 50's respectively for the nightly lows, and with west-southwesterly winds of around 5-10 mph.
Following this frontal passage our work week will start off a smidge cooler with temperatures hovering in the upper 70's for the first half of the week along with partly cloudy conditions. Although the cold front will be beyond us come Sunday night, the aforementioned "river" of moisture will still be centered over us for Monday through Wednesday. This would explain the slightly cooler daytime temperatures as it is harder to heat up more saturated air, and likewise the slightly warmer nighttime temperatures as more saturated air "holds onto heat" better. This moisture also leaves the possibility of diurnally convected pop-up storms that will have the possibility of having some lightning associated with them. The timing of these should happen closer to the noon to afternoon hours.
Thank you for reading! I hope everyone keeps cool on this Hump Day!
