NEAR TERM UPDATE /Now Through Friday/...An upper ridge will remain over the area through Friday. This will maintain the dry conditions with gradually warming temps. An increase in clouds can be expected tonight as high clouds spill over the ridge. However, no precipitation is expected. Lows tonight fall into the low 50s inland to around 60 near the coast. Highs on Friday warm into the upper 70s and low 80s inland to mid 70s along the coast. /13

Short Term - Friday Night Through Sunday Night
Weak shortwave ridging within zonal flow aloft will generally continue across the region during the Friday night through Sunday night period. A weak surface ridge of high pressure will remain over the area Friday night into Saturday, before the ridge axis shifts toward the east coast late in the weekend. A dry surface airmass will remain in place across the forecast area Friday night through Saturday. Moisture through the deep layer also remains limited during this time frame underneath shortwave ridging aloft, so we will maintain the dry forecast through Saturday afternoon. Short range operational model solutions continue to show pattern differences during the Saturday night-Sunday time frame, as the GFS continues to show a more pronounced shortwave trough within the mid level flow crossing the region during this time, while the ECMWF (European Centre for Medium-Range Weather Forecasts) solution favors a drier forecast. Both solutions do show increase in boundary layer moisture, especially over our central-southern CWA, so have kept low POPs in the forecast over all but perhaps our N/NE zones Saturday night-Sunday in line with the NBM guidance. Temperatures remain warm through the weekend. Lows Friday night range in the mid to upper 50s inland and in the lower 60s near the immediate coast, warming into the upper 50s to lower 60s inland and in the mid 60s near the coast by Saturday night. Highs Saturday and Sunday are forecast to reach into the upper 70s to mid 80s. /21

EXTENDED TERM /Monday Through Thursday/...A quasi-zonal flow pattern will persist across our region through the middle of next week to the north of an upper level ridge of high pressure building over the southern Gulf. Periodic shortwave troughs embedded within the flow will move across the north central Gulf Coast region each day, though the timing of these impulses will dictate where the best chance of showers and thunderstorms each day. For now, we kept the best chance of showers/storms located over interior areas on Monday through Wednesday where deeper moisture and ascent appear to be favored with shortwave trough progression each day early to mid next week. An upper level trough/low may deepen over the southwestern states late next week, but the depth and eventual track/timing of ejection of this next system is still highly uncertain late next week into next weekend. For now the medium range guidance continues to signal enough moisture within the pattern aloft to keep a continued chance of showers and storms in the forecast into next Thursday. Temperatures otherwise continue to average well above normal next week with highs warming back into the 80s, with morning lows only in the 60s and perhaps in the lower 70s in some places by Wed-Thu. /21
