Conditions will remain hot and dry out there, daytime highs will top out around 110° on Monday, while overnight lows generally cool to the 70s. Monsoon moisture will also begin to increase on Monday, mainly above 500mb, so a high based shower or thunderstorm is possible with primary threats being strong, gusty winds and lightning.
A moist south-southeast flow will develop through the middle of the week with moisture increasing down to 700mb, shifting the focus on storms to heavier rainfall with flash flooding potential, especially Wednesday through Friday.
We'll also have to watch for additional moisture from Tropical Storm Flossie in the Eastern Pacific and the Gulf. This could elevate the flash flooding potential through the Independence holiday. Moisture may decrease a bit over the weekend, but scattered showers and thunderstorms will remain possible mainly during the afternoons & evenings. |
