PREV DISCUSSION. /Issued 237 PM EST Fri Mar 5 2021/

SHORT TERM /Tonight through Saturday Night/ . The main feature in the short term period is a closed upper-level low that will dive southeastward through the ArkLaTex today, then transition to a shortwave trough as it pushes across MS/AL/GA tonight through tomorrow. A surface low will develop in the northern Gulf tomorrow in response to the upper-level forcing, but the low will remain well south of the CWA as high pressure builds into the state from the north. As a result, moisture will be quite limited across the CWA tonight and Saturday, with PWATs generally under 0.5 inch. CAMs suggest the possibility for some sprinkles across the CWA tonight, but given the mid-level cloud deck that will be in place with dry air from ~700 mb to the surface, I am maintaining essentially no PoPs across the CWA. Lows will range from the mid- and upper 30s north, to lower to mid-40s south.

Saturday will bring a transition to northwest flow aloft as the aforementioned system exits to our east. Mid-level clouds will gradually clear through the late morning and early afternoon, keeping highs capped in the lower 50s to near 60. Lows heading into Sunday morning will be in the upper 20s to upper 30s.

LONG TERM /Sunday through Friday/ . High pressure and dry conditions are anticipated for the extended portion of the forecast. There is some potential into next weekend for some isold/sct shra up north, but coverage at this time remains low.

High pressure will build in from the west on Sunday and remain the dominant weather feature for the next seven days. The ridge axis is expected to slide offshore by the middle of next week, with the surface flow switching to are more southerly direction, increasing the low level moisture. Below normal temperatures are anticipated through the weekend, but he warm up begins next week with values well above normal for this time of year expected.

FIRE WEATHER. Cloud cover associated with a passing upper-level system tomorrow (Saturday) will mitigate fire weather concerns, but the northern tier of the forecast area will still need to be monitored for minimum RHs approaching ~25%.

Low RH values are expected to continue into the weekend, but winds will remain below any critical values. NW winds on Sunday should switch over to the NE overnight Sunday or early Monday morning. Winds will remain easterly through the end of the week. By Thursday/Friday, winds may try to go more S/SSW. Wind speeds through the period should be fairly light across most locales and averaging 10mph or less.

AVIATION. 00Z Update . VFR conditions through the evening with high level clouds starting to move across the metro TAF sites. Winds expected to shift to the NE around 08z tomorrow in addition to lowering clouds. There is the potential for a brief period of BKN MVFR cigs for a couple hours tomorrow afternoon ~17z-19z before going FEW by 22z. Winds expected to go NNE to NNW by late tomorrow afternoon. Winds should remain between 4-8kts through the period.

//ATL Confidence . 00Z Update . Low confidence on MVFR cigs. Medium confidence on timing of wind shift. High confidence on all other elements.
