Default 1800 MetO analysis and forecast thoughts

Looking at the 1800 sea level pressure analysis from the MetO at wetterzentrale
it shows a frontal system with triple point over SW England but with hardly any
pressure gradient round it as the parent low is now well out to the west.
Rainfall radar at 2100 shows narrow bands of rain in the south which
surprisingly are not moving very far.

I'm beginning to wonder whether eastern England including the SE will see any
frontal rain at all ? It's also possible that there won't be much to kick off
showers either until Wednesday. In the SW nearer the parent low, troughs
swinging round could trigger heavy showers earlier. I think what I'm trying to
say is that for this severe weather event to come off something rather subtle
and not obvious from the available charts on the net has to happen. The
*potential* is still there of course, very warm and extremely moist air near the
surface just waiting for a trigger. A very tricky situation to forecast.

Personally I had low confidence last thursday and I still have low confidence in
any prediction. Forecasting in summer can be a real swine sometimes.

Will.
