0:00:02 > 0:00:05Thanks for joining me. Very quiet on the weather front across the UK,
0:00:05 > 0:00:07but before we go into the details,
0:00:07 > 0:00:10let's just get a quick update on Hurricane Matthew.
0:00:10 > 0:00:12Of course has caused a lot of devastation,
0:00:12 > 0:00:15it has been devastating that Florida coast into Georgia
0:00:15 > 0:00:17and South Carolina, but the storm's weakening now
0:00:17 > 0:00:20and we're thinking that it's going to pull out into the Atlantic
0:00:20 > 0:00:22and then possibly loop back down again
0:00:22 > 0:00:23as a much, much weaker storm.
0:00:23 > 0:00:26So it's not over yet, this story's going to continue,
0:00:26 > 0:00:27but it is a dying storm.
0:00:27 > 0:00:30Still powerful at this stage, though.
0:00:30 > 0:00:32Back home, what have we got?
0:00:32 > 0:00:35Well, we've got an area of high pressure that's driving our weather
0:00:35 > 0:00:38but also this area of low pressure is sending a breeze in our direction
0:00:38 > 0:00:41and that actually was responsible for a few heavy showers
0:00:41 > 0:00:44across south-eastern areas of the UK during the course of Saturday.
0:00:44 > 0:00:48And actually, we're going to see a very similar pattern on Sunday -
0:00:48 > 0:00:50a breeze will continue to blow in a few showers,
0:00:50 > 0:00:52you see it's picking up moisture off the North Sea
0:00:52 > 0:00:54and then sending these showers in our direction,
0:00:54 > 0:00:57so anywhere from Newcastle, Hull, down into London
0:00:57 > 0:00:59we could catch a few. The best of the weather will always be
0:00:59 > 0:01:02across western areas - this is where you're going to get more sunshine.
0:01:02 > 0:01:04Then Sunday night into Monday,
0:01:04 > 0:01:07the winds will be light, generally, inland,
0:01:07 > 0:01:09not necessarily light along the east coast -
0:01:09 > 0:01:11we might even have further showers here.
0:01:11 > 0:01:14The basic message is, it is going to be quite a chilly night,
0:01:14 > 0:01:17Sunday night into Monday, and first thing, particularly in rural areas,
0:01:17 > 0:01:19so we're talking about the frost hollows, frost pockets,
0:01:19 > 0:01:22there might be some mist, a bit of ground frost in one or two areas,
0:01:22 > 0:01:25but that's going to be the exception rather than the rule.
0:01:25 > 0:01:27But Monday morning is going to be nippy.
0:01:27 > 0:01:30Then that same pattern continues - that low pressure
0:01:30 > 0:01:32that we saw earlier on out there towards the east
0:01:32 > 0:01:34is still sending a breeze in our direction,
0:01:34 > 0:01:36picking up the moisture off the North Sea,
0:01:36 > 0:01:38so again we'll see some showers.
0:01:38 > 0:01:40Some will penetrate quite deep inland, into the Midlands,
0:01:40 > 0:01:43but these western areas will have the best of the weather.
0:01:43 > 0:01:46Northern Ireland might actually catch quite a bit of cloud
0:01:46 > 0:01:47and there could be some spots of rain.
0:01:47 > 0:01:48That pattern is still with us,
0:01:48 > 0:01:50so we've got the high across Scandinavia,
0:01:50 > 0:01:53there are sort of weather fronts stuck in its southern periphery,
0:01:53 > 0:01:56and this low, which we're going to talk about a little bit later on,
0:01:56 > 0:01:58that's trying to push in, but not just yet.
0:01:58 > 0:02:00So here's Tuesday,
0:02:00 > 0:02:02and one thing that you will notice on Tuesday
0:02:02 > 0:02:05is that the wind is going to be picking up,
0:02:05 > 0:02:06so actually for some of us,
0:02:06 > 0:02:09particularly for folks along these eastern coasts,
0:02:09 > 0:02:12it is going to feel cool with that increasing breeze,
0:02:12 > 0:02:14which will increase, actually, even further
0:02:14 > 0:02:16as we head into Wednesday.
0:02:16 > 0:02:18In fact, round some of the coasts and headlands,
0:02:18 > 0:02:21it could be rather windy, and only 13 degrees
0:02:21 > 0:02:23with a stiff easterly will feel pretty nippy.
0:02:23 > 0:02:25One of the reasons we have a strong wind is,
0:02:25 > 0:02:27look at these straight isobars.
0:02:27 > 0:02:29We quite often talk about isobars tightly packed together,
0:02:29 > 0:02:32but we don't talk about the shape an awful lot.
0:02:32 > 0:02:36Straight isobars often mean quite strong winds.
0:02:36 > 0:02:37Imagine sort of like running down a motorway.
0:02:37 > 0:02:40When you get curved isobars, just like round a roundabout,
0:02:40 > 0:02:43you tend to slow down, the winds quite often slow down.
0:02:43 > 0:02:45When you have straight isobars, you get a stiff wind.
0:02:45 > 0:02:48Now, this low here that we've been looking at is trying to push in.
0:02:48 > 0:02:51Here it is, say round about Friday time -
0:02:51 > 0:02:54tries to push in but is still stuck.
0:02:54 > 0:02:58Let's have a look at this in a little bit more of a schematic way.
0:02:58 > 0:03:01This is called an omega block.
0:03:01 > 0:03:05You have to kind of squint to see the letter omega here,
0:03:05 > 0:03:06but it is there.
0:03:06 > 0:03:09When that happens, the weather's stuck in a rut,
0:03:09 > 0:03:10so the high pressure's not moving anywhere,
0:03:10 > 0:03:13it's kind of sitting there, the low pressure's trying to come in,
0:03:13 > 0:03:16and the thinking is it might sort of squeeze in Friday into the weekend.
0:03:16 > 0:03:20But until that happens, for now, it's looking mainly dry,
0:03:20 > 0:03:23rather cloudy, and remember those straight isobars?
0:03:23 > 0:03:26It is going to stay on the breezy side
0:03:26 > 0:03:28with some chilly mornings as well. Thanks for watching.
