UPDATE. For 00Z Aviation.
SHORT TERM. /Updated at 1135 AM CST Sun Mar 07 2021/ Through Monday.
Very few changes were necessary regarding the short-term forecast as things are currently on track as we approach midday. The very dry northeasterly flow at the surface continues to dominate the pattern over the Southeast. Dew points were currently running in the 20s with a few upper teens across far eastern counties. The dry air will allow temps to rise well into the 60s areawide this afternoon. We've had a few gusty winds out there today, but overall winds haven't been quite as strong across the area as we observed yesterday.
We'll see more radiational cooling once again tonight, with mostly calm and clear conditions. Much like last night, areas that are allowed to decouple will see frost or freeze conditions. Our big warm up will begin on Monday as upper heights will be on the increase and the surface ridge will be centered off to our east. Southerly flow at the surface with lingering dry air will allow the airmass to heat very well, and we'll stay on the higher end of guidance in terms of afternoon highs. We'll likely see an abundance of lower 70s across much of Central Alabama under mostly sunny skies.
LONG TERM. /Updated at 343 PM CST Sun Mar 07 2021/
No major changes were made to the extended with no mentioned rain chances through Friday. The dry trend continues with rain pushing back some. Low rain chances return on Saturday across the north and west ahead of an approaching frontal system. A warming trend will continue through Friday. Clouds do return Tuesday into Wednesday as ridging weakens and onshore flow returns through the end of the work week.
Previous long-term discussion: /Updated at 321 AM CST Sun Mar 07 2021/ Tuesday through Saturday.
Warm and dry weather will continue through much of the upcoming week.
High pressure will persist across the region Tuesday into Wednesday, leading to synoptic subsidence and, therefore, rain- free conditions. The drier air mass that has been in place will continue to allow for slightly larger diurnal temperature swings than we typically see - lows in the 40s with highs in the 70s.
The center of the high pressure system will shift eastward Wednesday into Thursday as a trough digs southward along the Pacific Coast. This shift in the high will allow for more southerly flow across our region, leading to a slight increase in moisture. However, the flow is largely off the Atlantic and never crosses a significant fetch of the Gulf, so our dewpoints will likely stay in the 50s through the end of the week.
The trough across the Western CONUS develops into a cut-off low and progresses eastward very slowly through the end of the week. Model guidance has not shown much consistency at all with the timing and evolution of this upper low and trough. Latest deterministic runs bring in broad ridging in the Gulf of Mexico Thursday into Friday, which would act to deflect any shortwaves ejecting from the trough northward, keeping any significant rain changes north and west of Central AL. With that said, models continue to try to bring some rain into the area toward the end of the extended, but with each model run, the timing is pushed back, so I'll once again include low chance (15-20%) PoPs for the day 7 period (Saturday) and reduce any rain chances we had for Friday. I would expect this to change again as models come into better agreement. Our warmest days will likely be Thursday or Friday with high temperatures reaching into the upper 70s to low 80s.
AVIATION. 00Z TAF Discussion.
VFR conditions will continue through the forecast period. Surface high pressure will slowly settle over the state the next 24 hours. Winds will drop quickly to light or calm overnight. On Monday, winds will be light and variable for the most part. Some of the southern and western sites may experience winds east to southeast by periods end but still light.
Min RHs through Monday afternoon is forecast to be near or just below 20%; however, if sufficient mixing occurs or if temperatures warm even a few degrees above what's forecast, the RHs could drop even lower. KBDI's are below 300 with 20 foot winds 7 mph or less, so no red flag products are anticipated. Gradual increase in moisture is expected Tuesday through Friday as we see more of a southerly flow.
