BRACKNELL (TAWFIELD)
0900 SSE F3 30km - 1/AC 3/AC 5/CI T242D162
RMK: [CAVOK] - 1Ac cas (actually almost a 'trace')~100: this latter was
a much more definite element of the medium levels up to about an hour
ago, 3Ac (thinning/increasingly broken)~120 (the retreating western edge
of a multi-level sheet that dominated the sky earlier), 5Ci, thick
sheaves etc., ~250/280. Given the cloud character earlier and now, I
guess a well-marked upper trough/front has passed overhead (from the
west), and the marked descent to the rear has killed off the mid-level
activity. For a time around 06Z, we had 1Cu med~060 development, but
that rapidly fizzled.
[ OVERNIGHT DATA (18Z - 09Z):
screen min: 17.2 grass min: 14.7 precipitation: NIL [24hr total: 00.0
mm]
other data: Probably going to be the best part of the day - high
humidity, but not (yet) too warm. ]=
