Version 3.4 |
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. 6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. |

Updated national weather service mobile al 1227 pm cdt Fri apr 20 2018 Discussion See updated information for land areas and aviation discussion below. Update The current forecast is on track and no changes are needed. 13 Aviation 18z issuance...VFR conditions will prevail through the next 24 hours. 13 Prev discussion issued 653 am cdt Fri apr 20 2018 discussion... See updated information for marine areas and aviation discussion below. Marine... Updated the coastal waters forecast this morning to extend the small craft advisory for a few more hours. Originally set to expire at 6 am, extended until 9 am as winds at middle bay lighthouse and buoy 12 still both frequently gusting to 18-21 knots shortly before 6 am. Do expect winds to diminish slightly after 9 am this morning, but small craft should continue to exercise caution through most of today as winds will continue to occasionally gust to 15 to 20 knots. 12 ds aviation... 20 12z issuance...VFR conditions expected to continue through the forecast period with only scattered mid and high level clouds. Surface winds initially northeasterly this morning, becoming more east and maybe even southeasterly near the coast late today and tonight. 12 ds prev discussion... Issued 423 am cdt Fri apr 20 2018 near term now through Friday night ... The reinforcing cold front that passed through the forecast area yesterday is now well to the south over the gulf of mexico, with cool and dry surface high pressure ridging into the area from the north. The surface high pressure will drift east through tonight, with a light to occasionally moderate northeast to east windflow expected with only slight low level moisture return. Ridging aloft is expected to increase from the west through tonight, maintaining the stable conditions over the area. Only scattered and mainly thin mid to high level clouds expected through the period. Should have plenty of sunshine today, but high temperatures should be slightly below normal, generally in the low to mid 70s. Lows tonight a little below normal as well, especially over inland areas where temps should fall into the upper 40s and lower 50s overnight. Near normal low temps tonight closer to the coast, where upper 50s are expected. 12 ds short term Saturday through Sunday night ... Short wave upper level ridge axis from the gulf, northward across the tn valley Saturday morning moves to the southeast as upper level storm system over the plains ejects eastward. A slight moderation in highs on Saturday. Upper level height falls associated with the plains storm system overspread the lower ms river valley Saturday night, then across the tn river valley southward to the gulf coast Sunday morning. At same time, a well established diffluent flow aloft moves atop the area. This favors an increase in deep layer ascent as a cold front associated wave of frontal low pressure approach from the west Sunday within a zone of much improved deep layer moisture. Weather models are in fair alignment on this morning's runs, showing complex frontal low positioned from ar to |
western ms Sunday morning, tracking only very slowly eastward during the day. Ahead of this feature, despite strengthening low level wind shear, there is substantial spread in the models on amount of buoyancy daytime instability that will be available Sunday. The operational gfs ECMWF shows 0-1 km CAPE generally from 200 to 400 j kg with the NAM output on MUCAPE building its values from 700 to 1100 j kg by late in the day Sunday. The short range ensembles for CAPE greater than 500 j kg shows a general 30 to 60% probability of occurrence over the local area. Considering the differences mentioned, the risk of severe weather is marginal. Highest rain chances (categorical pops) move from west to east during the day Sunday. Best deep layer ascent begins to shift east Sunday evening with showers likely and a few storms over the eastern zones and a mid range chance west. Daytime highs on Sunday trend lower given thickened cloud cover and high rain chances. 10 long term Monday through Thursday ... Frontal passage occurs Monday morning as surface frontal low eases across southeast al and southern ga. A small chance of showers north of the coast Monday morning in the wrap-around moisture on the west side of the low. The low lifts northeast up across the carolinas on Tuesday and quickly up across the DELMARVA on Wednesday. A slight chance showers remain in the forecast over the far northern zones Tuesday as secondary short-wave energy aloft at the base of southern states long-wave trof passes through, combined with lingering wrap around moisture on the west side of departing low. Next front looks to make passage late Wednesday into Thursday bringing another small chance of showers to the local area. Daily highs not far off seasonal normals. Overnight lows trend close to seasonal by the middle of next week. 10 marine... A strong northeasterly wind flow over the marine area early this morning will weaken slightly today. A small craft advisory is in effect until 6am this morning for the gulf marine zones as well as southern mobile bay and the mississippi sound, and may have to be extended for at least a few more hours this morning. Will monitor trends and make that change a little later in the shift in necessary. Even after the SCA conditions subside sometime this morning, still expect exercise caution conditions to prevail over most of the marine area through most of the morning hours today (with winds of 15 to 20 knots) before gradually decreasing late today. A light to moderate easterly flow is anticipated for tonight, but gradually increasing somewhat again on Saturday as another frontal system develops to the west of the marine area. A moderate to sometimes strong southeast to south flow is expected Saturday night into Sunday as the front approaches. Winds become westerly in the wake of the front by Monday, with a light to moderate west to northwest flow then continuing into the middle part of mid next week. Showers and thunderstorms are expected ahead and along the front this weekend, with this best coverage occurring Sunday and Sunday night. 12 ds Mob watches warnings advisories Al... None. Fl... None.
