Yes you could do it but this option is depending on your received dataset, i checked yours but in this dataset you got back it's givving you timeframes of 6 hours, so you cant use that, i would search for a more detailed weather API ..

BR,

If someone is interested in then there's yrno script below (warning: uses obsolete API)
Function minmax_temp_tomorrow returns lowest and highest temperature for tomorrow. The script is simple and ignores time shift.

Code:

require('socket.http') forecast = {} function parsetag(parser, tag, attributes)  if tag == 'time' then    table.insert(forecast, {})    forecast[ #forecast ].from=attributes.from    forecast[ #forecast ].to=attributes.to    forecast[ #forecast ].period=attributes.period  elseif tag == 'symbol' then    forecast[ #forecast ].symbol = attributes.name  elseif tag == 'precipitation' then    forecast[ #forecast ].precipitation = attributes.value  elseif tag == 'windDirection' then    forecast[ #forecast ].wind_direction = attributes.code  elseif tag == 'windSpeed' then    forecast[ #forecast ].wind_speed = attributes.mps  elseif tag == 'temperature' then    forecast[ #forecast ].temperature = attributes.value  elseif tag == 'pressure' then    forecast[ #forecast ].pressure = attributes.value  end end function yrno_fetch()  local url = 'http://www.yr.no/place/Czech_Republic/Prague/Prague/varsel.xml'  local data, err = socket.http.request(url)  if data then    require('lxp').new({      StartElement = parsetag    }):parse(data)          else    alert('Fetch failed: ' .. tostring(err))  end end function minmax_temp_tomorrow()  local ld_minTemp  local ld_maxTemp  local next_day={}  yrno_fetch()  if (not forecast) then    return  end  local ll_tomorrow=os.time()+24*3600 -- tomorrow as long  local lt_tomorrow= os.date("*t",ll_tomorrow) -- tomorrow as table for use if forecast_write  --gets date of tomorrow  local ls_match=os.date("%Y--%m--%d",ll_tomorrow)   for index, value in ipairs(forecast) do    if (value.from:match("^"..ls_match)) then      local ld_temp=tonumber(value.temperature)      if (ld_minTemp == nil) then        ld_minTemp=ld_temp      end      if (ld_maxTemp == nil) then        ld_maxTemp=ld_temp      end      if (ld_temp<ld_minTemp or index==1) then        ld_minTemp=ld_temp      end      if (ld_temp>ld_maxTemp or index==1) then        ld_maxTemp=ld_temp      end    end end   return ld_minTemp,ld_maxTemp,lt_tomorrow end

You have to replace URL with the one that corresponds to your location.

Code:

require('socket.http') forecast = {} function parsetag(parser, tag, attributes)  if tag == 'time' then    table.insert(forecast, {})  elseif tag == 'symbol' then    forecast[ #forecast ].symbol = attributes.name  elseif tag == 'precipitation' then    forecast[ #forecast ].precipitation = attributes.value  elseif tag == 'windDirection' then    forecast[ #forecast ].wind_direction = attributes.code  elseif tag == 'windSpeed' then    forecast[ #forecast ].wind_speed = attributes.mps  elseif tag == 'temperature' then    forecast[ #forecast ].temperature = attributes.value  elseif tag == 'pressure' then    forecast[ #forecast ].pressure = attributes.value  end end url = 'http://www.yr.no/place/United_Kingdom/England/London/varsel.xml' data, err = socket.http.request(url) if data then  require('lxp').new({    StartElement = parsetag  }):parse(data)  log(forecast) else  alert('Fetch failed: ' .. tostring(err)) end

Here's a short example, change key variable to your API key, location variable to required location in textual form. This example fetches current weather condition and forecast for today and tomorrow. Fields can be found in apixu documentation: https://www.apixu.com/doc/forecast.aspx (day Element).

Code:

require('json') https = require('ssl.https') escape = require('socket.url').escape key = 'my_api_key' location = 'my location name' url = 'https://api.apixu.com/v1/forecast.json?key=%s&q=%s&days=2' url = string.format(url, key, escape(location)) res = https.request(url) data = json.pdecode(res) if type(data) ~= 'table' then  alert('failed to load weather data')  return end if data.error then  log('error', data.error)  return end current = data.current today = data.forecast.forecastday[ 1 ].day tomorrow = data.forecast.forecastday[ 2 ].day -- log(current, today, tomorrow) -- temperature in C grp.write('32/1/1', current.temp_c) -- "feels like" temperature in C grp.write('32/1/2', current.feelslike_c) -- humidity as percentage grp.write('32/1/3', current.humidity) -- wind speed in kilometers per hour grp.write('32/1/4', current.wind_kph) -- uv index grp.write('32/1/5', current.uv) -- weather condition text grp.write('32/1/6', current.condition.text) -- pressure in millibars grp.write('32/1/7', current.pressure_mb) -- precipitation amount in millimeters grp.write('32/1/8', current.precip_mm) -- minimum temperature in celsius for the day grp.write('32/2/1', today.mintemp_c) -- maximum temperature in celsius for the day grp.write('32/2/2', today.maxtemp_c) -- average temperature in celsius for the day grp.write('32/2/3', today.avgtemp_c) -- average humidity as percentage grp.write('32/2/4', today.avghumidity) -- maximum wind speed in kilometers per hour grp.write('32/2/5', today.maxwind_kph) -- uv index grp.write('32/2/6', today.uv) -- weather condition text grp.write('32/2/7', today.condition.text) -- total precipitation in millimeters grp.write('32/2/8', today.totalprecip_mm) -- minimum temperature in celsius for the day grp.write('32/3/1', tomorrow.mintemp_c) -- maximum temperature in celsius for the day grp.write('32/3/2', tomorrow.maxtemp_c) -- average temperature in celsius for the day grp.write('32/3/3', tomorrow.avgtemp_c) -- average humidity as percentage grp.write('32/3/4', tomorrow.avghumidity) -- maximum wind speed in kilometers per hour grp.write('32/3/5', tomorrow.maxwind_kph) -- uv index grp.write('32/3/6', tomorrow.uv) -- weather condition text grp.write('32/3/7', tomorrow.condition.text) -- total precipitation in millimeters grp.write('32/3/8', tomorrow.totalprecip_mm)

Code:

location = 'patra, greece'

For widget you will need to create a separate html page, upload it via ftp and then display by using iframe element.
