I see the official forecasters are getting a bit wound up (deliberate pun there) about a new Storm Doris, expected to cross the middle of the country on Thursday morning, bringing widespread gales and up to hurricane force winds across a central belt stretching from Lancashire to Lincolnshire, Norfolk and Suffolk. Fortunately there'll be a neap tide accompanying, so no danger of flooding from the North Sea; but if this does come off, it'll be an unusual one in my experience: normally for the type of "explosive cyclogenesis" (exceptionally rapid intensification of a low pressure system) to take place would involve either exceptionally warm long-distance winds of tropical origin approaching in advance of the low, (October 1987), or very cold arctic air incursioning at the rear. Neither appears to be the case - just a sudden increase in the velocity of the high-level jetstream, which will then quickly return to more usual speeds as it introduces slightly colder northwesterlies than the kinds of temperatures one would expect at the end of Feb, these not being of arctic origin and backing around into a westerly quadrant. All very strange.
It's a bronze severe weather warning for that central zone, so button down the hatches!
