12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

LATEST UPDATE . Aviation
SYNOPSIS. Issued at 329 AM EDT Sat Jul 4 2020
-Hot and dry pattern persisting; high fire danger
-Oppressive heat indices possible next Wed-Fri
-Next decent chance of rain not until next Friday
DISCUSSION. (Today through next Friday) Issued at 329 AM EDT Sat Jul 4 2020
-- Hot and dry pattern persisting; High fire danger --
Little change in the overall pattern into early next week at least with ridging/subsidence and dry air mass prevailing. Persistence fcst the way to go until further notice with mostly sunny skies and highs in the lower 90s. Fortunately the dew point and heat index remain relatively tolerable and shy of advisory criteria. Lack of rainfall and very dry conditions coupled with the hot/dry weather will keep the fire danger elevated for the next several days. Fortunately winds will remain light as sfc ridging persists.
While an isolated shower or storm cannot be completely ruled out over the holiday weekend, especially late in the day on the lake breeze front, will run with a dry fcst. Even if something did manage to develop, coverage would be so low (on the order of 5%) that it's probably not worth mentioning in the fcst. Will not carry any pops until next Tuesday and beyond, but even that's questionable and coverage should be widely scattered at best through next Thursday.
-- Oppressive heat indices possible next Wed-Fri --
Medium range guidance suggesting dew points closer to 70 for the middle to late part of next week, with the center of the upper high settling on top of us again. Heat indices 100-105 look more achievable during this time frame, which would require heat headlines.
-- Next decent chance of rain not until next Friday --
Upper pattern looks more conducive to organized convection by next Friday as upper ridge is suppressed south and faster/flatter pattern takes shape aloft. Thus at this time the highest pops in the next 7 days looks to be next Friday as better deep layer shear and an approaching sfc front interact with our hot/humid/unstable environment.
AVIATION. (For the 12Z TAFS through 12Z Sunday morning) Issued at 735 AM EDT Sat Jul 4 2020
VFR continuing, with light east-northeast sfc winds of 4-8 kts. However northwest winds around 10 kts expected at MKG by mid afternoon into the early evening. Some patchy fog could develop late tonight, but the threat is too low to include any vsbys restrictions in the TAFs at this time.
MARINE. Issued at 329 AM EDT Sat Jul 4 2020
Minimal marine concerns over the next several days with sfc riding continuing to prevail. Periods of briefly higher onshore winds expected from mid afternoon into early evening due to diurnal lake breeze circulation.
