    Been bone dry in Raleigh for weeks. We can soak it up.

    Same here in Hickory, NC. We got 0.62 inch of rainfall last night due to a rogue storm on the frontal passage, but that was the first measurable rainfall in weeks. We need the rain here.

    Last measurable rain IMBY was Sept 12th. Only 1.52" for the month so far. Not bothering aerating the lawn, it's hard as a rock.

  2. FWIW I was in Morrisville/Briar Creek this afternoon and the Apple Watch said 97... not sure if that data came from KRDU though. High of 96 at the house in south Cary, I can believe 98.

    No precip recorded today IMBY, only some good breezes. Currently 76 and falling.

    Closer to the coast, nasty looking "S" shaped cell near NWS Newport right now. Should make for some interesting winds and waves tomorrow.

     

  3. The NHC's "squished-Mercator-ish" map (I'm no cartographer) looks really weird when it has to be stretched from the mid-Atlantic to the Arctic Circle. I also noticed they didn't bother marking the wind speed probabilities above 60N. First time I think I've seen that cutoff.

  4. From Canadian Hurricane Centre:  4-8" of rain and 30+ foot waves in the Gulf of St. Lawrence

    Fiona expected to impact Atlantic Canada and eastern Quebec with heavy rainfall and powerful hurricane force winds for the start of the weekend.

    .....

    2. Public weather impacts and warnings summary.

    This storm is shaping up to be a potentially severe event for Atlantic Canada. Numerous weather models are quite consistent in their prediction of what we call a deep hybrid low pressure system, possessing both tropical and intense winter storm-type properties (but with very heavy rainfall and severe winds).
    The latest forecast guidance brings hurricane Fiona off-shore to the south of Nova Scotia Friday night, passing through eastern Nova Scotia and Cape Breton Saturday, and then reaching the Lower Quebec North Shore and Southeastern Labrador early Sunday. Severe winds and rainfall will have major impacts for eastern Prince Edward Island, eastern Nova Scotia, western Newfoundland, eastern Quebec, and southeastern Labrador. There will also be large waves, especially for the Atlantic coasts of Nova Scotia and Newfoundland and eastern portions of the Gulf of St. Lawrence. Finally, there is a high likelihood of storm surge for parts of Nova Scotia, Gulf of St. Lawrence and Newfoundland.

    a. Wind.

    Most regions will experience some hurricane force winds. These severe winds will begin impacting the region late Friday and continue on Saturday. Similar cyclones of this nature have produced structural damage to buildings. Construction sites may be particularly vulnerable. Wind impacts will likely be enhanced by foliage on the trees, potentially causing prolonged utility outages

    b. Rainfall.

    Rainfall will be significant, especially north and west of Fiona's track, where heavy rainfall could lead to flooding. the highest rainfall amounts are likely for eastern Nova Scotia, southwestern Newfoundland and the Gulf of St. Lawrence region. Forecast guidance is suggesting widespread amounts of 100 to 200 mm, but closer to the path of Fiona, more than 200 mm is likely. Some districts have received large quantities of rain recently, and excessive runoff may exacerbate the flooding potential.

    c. Surge/Waves.

    There will also be some rough and pounding surf, especially for parts of Nova Scotia and Newfoundland. Large waves will reach the eastern shore of Nova Scotia Friday night and build to more than 10 metres. These waves will likely reach southern Newfoundland by Saturday morning. Some of the waves over eastern portions of the Gulf of St. Lawrence could be higher than 7 metres. Waves will break higher along some of the coastlines, and dangerous rip currents are likely. Storm surge will also be a threat, for parts of Nova Scotia, Prince Edward Island, including Northumberland Strait, Gulf of St. Lawrence region including Iles-de-la-Madeleine, and southwest Newfoundland, but it is too early to provide details on which portions of the coastline may be affected the most.

    3. Marine weather impacts and warnings summary.

    Hurricane force southeasterlies should spread into Scotian Slope waters Friday evening, these hurricane force southeasterlies will persist near and south of the track. As the storm moves into the Maritimes, storm to hurricane force northwesterlies will likely develop behind it. Waves in excess of 12 metres should form south and east of the hurricane track, beginning Friday night. These large waves will likely reach the south coast of Newfoundland early Saturday, and parts of the Gulf of St. Lawrence later Saturday.

    3. Technical discussion
    
    A. Analysis
    
    Fiona, a category 4 hurricane, is continuing northward. The once well
    defined eye has been filling with cloud on satellite over the last
    few hours. Vigorous convection is continuing to wrap around the
    centre, with satellite derived cloud top temperatures nearing - 80c
    in the northwestern quadrant. An area of convection well to the
    northeast of the centre is also evident on satellite at this time.
    Maximum sustained winds are held at 115 kts, and the central pressure
    is estimated at 937 MB.  The motion is northward at 7 knots.
    
    B. Prognostic
    
    The environment will likely support slight intensification in the
    next day or so, as the hurricane travels in a moist environment over
    very warm waters under light to moderate wind shear. Beyond 18 hours,
    the model consensus begins to accelerate as an upper trough
    approaches from the west, bringing the hurricane near Sable Island
    Friday night as it undergoes extra-tropical transition. Then
    post-tropical storm Fiona is expected to make landfall over Cape
    Breton Island Saturday morning while maintaining sustained hurricane
    force winds.  The forecast track has been shifted slighty westward
    with this update, to reflect the tight clustering of guidance
    ensemble members over Northern Cape Breton. The cumulative qpf field
    from the rdps/gdps suite is indicating a pre-cursor rainfall event
    well ahead of the centre beginning as early as Friday morning or
    afternoon. Rainfall totals suggested by the main models is showing
    more than 200 mm north and northwest of the track.

  5. High of 86 today with .29" of rain. Felt like mid-July. Looking forward to the week ahead. Meanwhile, my maple trees have shed about 30% of their leaves. I don't see any signs of disease, my first thought is the worse than usual flood/drought pattern this year.

  6. Closed out August with 4.08" of rain. Monthly high of 98.2 on August 3rd, low of 60.0 on August 13th.

    As for today, 63.4 at 7:15am this morning. Dare I say - a little chill for shorts and flip flops!

    Looking back at 2021, September gave me my first fall 40's with a low of 49 on September 24th. Firewood ready!

    Would be absolutely comical if the LAST possible advisory for August featured a system 

    If that happens they should name the system Rich Strike - that horse that almost no one expected to win the Kentucky Derby.

    Just the usual reminder that even in dead seasons like 1983 and 1992, major hurricanes can still hit population centers.  'A' storms that formed in August.  1992 a Cat 5 just South of MIA and a Cat 3 near KPTN.

    I was in FL for Andrew. Took some growing up to realize that was late for an "A" storm. Lots of lessons learned from that storm, one of them for me was putting tape on the windows doesn't do anything and is a b**** to remove in the post-storm heat and humidity. Family still throws their plastic patio furniture in the pool though, fun memories of sitting in underwater chairs.

    Wow what a difference being on the other side of the city makes. We’re at 6.32” and places north of here have more than that 

    I was out of town and missed the first good rain we had in a while on Saturday the 23rd (.31"). Picked up .50" yesterday and .20" today.
