Bermuda Weather Service Forecast Discussion
For Saturday, March 14, 2026
09:00 UTC
FORECASTER - Lawrence Doughty
NOWCAST: (Today and tonight)
Mostly settled conditions persisted overnight as the fragmenting
front lingers to the NW of Bermuda. Occasional cloudy skies look
set to continue today as bouts of low cloud and the odd light shower
persist into Sunday, increasing slightly overnight as the quasi-stationary
front becomes reinvigorated towards dawn. Above average temperatures
look set to continue within a light to moderate SSW`ly breeze that
gradually eases to become light and variable this evening. Winds
then settle to the ENE and increase towards moderate as high pressure
to the distant north causes an increasing pressure gradient squeeze.
Models show good overall agreement with marginal QPFs resulting from
the occasional shower into Sunday. Moderate seas match OPC data,
diminishing slight to moderate into this evening.
WATCHES, WARNINGS and ADVISORIES: None.
AVIATION: VFR conditions are expected to be occasionally interrupted
by MVFR/IFR conditions due to low ceilings and a few brief showers.
RWY 12 remains active with winds 190-210 5-9 knots becoming light
and variable later in the period. For more information visit: http://weather.bm/aviation/
SHORT TERM FORECAST: Sunday through Monday
Near-zonal flow aloft becomes broadly ridged on Sunday, lifting
the lingering front to the north and allowing early showers to dissipate
later in the day. Robust high pressure to the distant north slides
into the North Atlantic, causing a pressure gradient squeeze over
our area throughout the period. As a result, moderate ENE`ly wind
gradually veer and increase to become marginally strong at times.
Models show decent overall agreement, with the UK solution preferred,
however the EC and GFS show marginally strong winds lingering from
Sunday evening through Monday and therefore, the current Small Craft
Warning may need to be extended. Despite a mostly dry and bright
start to Monday, a few showers remain possible as nearby convergence
around the edge of the high, in combination with divergent flow aloft
which may help to develop a few showers, although model QPFs remain
marginal. Conditionally unstable atmospheric profiles also give the
slight chance of isolated thunder nearby on Monday, currently expected
to remain distant. Slight to moderate seas rebuild moderate on Sunday.
WATCHES, WARNINGS and ADVISORIES: A Small Craft Warning has been
issued for Sunday evening and again on Monday night for marginally
strong surface winds.
LONG TERM FORECAST: Tuesday through Wednesday
Tuesday sees sharpening upper troughing move off CONUS, with sympathetic
ridging overhead helping to maintain a dry wedge of air which allows
for sunshine to persist through much of Tuesday. A few showers gradually
develop into Wednesday as upper troughing sends a robust cold front
into our area on Wednesday morning, as the latest marine charts show.
The cold front sends scattered showers into the area on Wednesday
morning with up to an inch of rainfall possible according to the
latest UK model runs, whilst the EC and GFS remain slightly less
convinced. Bermuda remains on the forward side of upper troughing
as an Omega-block sets up across the Atlantic, causing the front
to stall nearby and maintaining cloudy skies and the chance of further
showers beyond the forecast period. Moderate to strong SSE`ly winds
veer SSW`ly into Wednesday morning as the front weakens, causing
winds to sharply veer N`ly and ease to become light and variable
overnight. Moderate to rough seas develop on Tuesday, persisting
into Wednesday.
WATCHES, WARNINGS and ADVISORIES: A Small Craft Warning is likely
required throughout the period. Slight chance of a Thunderstorm Advisory
for Wednesday morning.
