Monday weather forecast and weather information.
🔶AMBER WEATHER WARNING FOR WIND BETWEEN 1800 until 9am Monday 🔶
🔶KWT are issuing a weather watch for strong winds for Tuesday 🔶
What a week it's been so far from KWT publishing our own sleet and snow weather advisory at beginning of the week, and to end the week with mild temperatures and Storm Isha. Just when we thought it'll be safe to go out on Tuesday, the latest GFS weather models are showing another low pressure system (this could also be named) that has the POTENTIAL to bring further disruption and gales during Tuesday. At this stage, the charts are giving varied winds speeds outcomes with some at 40mph and others showing 70mph, so be prepared for more Met Office weather warnings this week.
The strong 200mph+ jet stream crossing the Atlantic, is being ‘fuelled’ by a steep temperature gradient across southern USA, very cold arctic air over much of central and eastern USA and warm air from the Gulf of Mexico, is which has created Storm Isha to form and move over the Atlantic ocean and will be over Northern Scotland by the time of posting this.
So at 19.30 this evening we have seen max gusts of 89mph near Padstow, but I'm sure there are plenty of places around Cornwall that have seen much stronger gusts. The whole of Cornwall is under an Amber weather warning for strong winds, with the peek of the winds, this evening into the early hours of Monday morning, when at around 3am, the winds will ease down although it will remain very blustery at between 40-70mph, with further bands of heavy showers, maybe some hail mixed in too, temperatures will sit between a balmy 9c and 13c.
For those travelling early on Monday morning, we may be playing dodge the wheelie/bins and bags with the possibility of fallen trees and branches on the back roads but some good news is that the winds will ease down, however, there will still be plenty of heavy to torrential showers around at times, with the occassional bright and sunny interval.
The rest of Monday will remain much the same, a further spell of heavy showers blowing in from a westerly direction, with a break in the weather allowing for some lovely bright or sunny spells.
The winds will remain blustery all day at 20-50mph with the strongest of the gusts being over higher grounds and coastal communities. The temperatures will between 7c and 11c maybe slightly warmer when the sun is out.
After dark on Monday, we continue with a feed of showers from the west, but these will slowly fade away as the night progresses, however, it will remain cloudy with a few clear spots here and there and the occassional shower too.
Tuesday, at the moment, has plenty of uncertainty although there is the potential for some more damaging winds on Tuesday night into Wednesday morning. Another system will move in from the west but we are unsure if the winds will be as severe as in Sunday night's system, although it is highly likely that we will at least see further wet and windy weather.
It's looking to be a bumpy week ahead, but as always, we'll keep you updated.
