The best weather is forecast for the south of the country with temperatures expected in the low to mid teens.
Dry and sunny spells will replace the wet and windy conditions experienced earlier in the week, forecasters say.
Although parts of the North East and Scotland will still be blustery, it is an improving situation and nothing that could potentially keep voters away from polling stations.
When asked if the weather is likely to have an impact on the outcome of the election, John Curtice, professor of politics at Strathclyde University, replied: “The answer is no.
“In the absence of a major storm of the kind that disrupts traffic and therefore people don’t get home by 10 o’clock in the evening, it doesn’t make a difference.
“We live in a country where a bit of drizzle is commonplace.”
The Met Office’s Marco Petagna said: “Away from the North East we can’t rule out an isolated shower, but it looks like being dry with sunny spells at times and much better than yesterday and today.
“It is still a little on the cold side, and we are generally looking at highs in the North West and Northern Ireland of about 8C to 11C.
“Across England and Wales it will be around 11C to 14C, and in some parts of the South East it could be 17C in one or two spots, which is above average for this time of year.
“There should be nothing to keep voters away - it will be much better than it has been today and yesterday.”
