Bermuda Weather Service Forecast Discussion

For Saturday, May 25, 2024  19:00 UTC

FORECASTER - Kimberley Zuill 

NOWCAST: This Evening through Tonight 
Early cloud once again gave way to brighter skies by midmorning 
as a ridge of high pressure elongated over us from the SW offering 
protection from the developing low which is advancing from the distant 
south. ASCAT pass indicated a vast region of light and variable winds 
within our weak pressure pattern. However, by midafternoon winds 
settled to the NE and began to feed a bubbling Reverse Morganís Cloud 
that built over the spine of the Island. As winds backed more N, 
the line of Cu shifted offshore and dissipated somewhat to leave 
a very pleasant evening. The upper ridging has moved out east and 
while upper troughing set in today, the features at the surface remained 
quite benign. The latest satellite imagery shows a shield of cloud 
spilling over from the low to our south. Radar imagery shows isolated 
tiny echoes outside of the 50km radius. Temperatures remain seasonal 
with typical high humidity. The latest OPC analysis has seas near 
2-3ft which agrees with model initialization.  
WARNINGS: No watches or warnings expected. 
AVIATION: VFR conditions. Wind NNE 5-8 knots, but may settle WNW 
overnight. No aviation hazards expected. For more information visit:

SHORT TERM FORECAST: Sunday through Monday
The elongated high pressure cell extending from SW-NE hangs over 
the area but is pushed out east as a low pressure system to the NW 
draws near. The low pushes unsettled weather overnight on Sunday 
that lingers through Monday with occasional showers.  In the upper 
levels, troughing slides out east and weak ridging develops with 
a more zonal flow into Monday, but another trough soon spills into 
the area to end the short term period. Conditions will be rather 
humid with maximum temperatures near 26-27C/79-80F. Light WNW winds 
back towards the SW overnight Sunday then occasionally shift WSW 
at times on Monday. Slight to moderate seas will abate slight by 
Sunday afternoon.  
WARNINGS: No watches or warnings expected.  

LONG TERM FORECAST: Tuesday through Wednesday 
Cloudy skies and light showers persist on Tuesday and finally lift 
away to the north on Wednesday leaving drier weather in its wake. 
It should be noted that a cold front is approaching the area but 
is still to the distant NW by Wednesday. In the upper levels, an 
upper high quickly passes north of the island on Tuesday ahead of 
another upper trough moving off CONUS which will bring cyclonic flow 
aloft on Wednesday. Maximum temperatures are likely to be near 26C/79F 
during the long term period. SW winds 5-10kt back Síly late night 
on Tuesday then increase to 10-15kt overnight on Wednesday. Slight 
seas build slight to moderate over the period.      
WARNINGS: No watches or warnings expected.
